Any fine weekend in Inishowen, Co Donegal, the roads are choc-a-bloc with day-trippers from the North flooding across the Border. They are heading to the beach, to hotels for a carvery lunch, or just out for a leisurely coffee or ice cream.
In ordinary times this activity wouldn't make headline news. But we're not in ordinary times and the reaction to last weekend's mass gatherings are still making headlines across Donegal days later.
Holiday homes and caravan parks across the county have also been filling up as Northern visitors decide to spend some of the lockdown in Donegal.
The fear and loathing generated by what happened at the weekend is enough to set cross-border relations back further than Brexit could over a period of months.
And while the fluidity of the Border has always been welcomed, in recent days the backlash has been swift. Even councillors in Donegal have got on the pitch to tell people to stay home.
In west Donegal, a vandalised road sign urged campervans to "fan sa bhaile", leading popular singer Mairead Ní Mhaonaigh of trad band Altan to state that "cop on" is what's needed.
While beaches and popular walking destinations all over the country were thronged at the weekend, the souring of cross-border relations is an added dimension to the packing out of the beaches in Donegal. As UK Prime Minister Boris Johnson rolls out stringent measures to stop the spread of coronavirus, ordering people to stay home, the earlier laissez-faire attitude of the British government contributed to people in Northern Ireland feeling that it was business as usual.
On this side of the Border, schools were closed over two weeks ago. Schools in the North stayed open. The difference in stance was breathtaking. In the Border village of Muff, Co Donegal, the local school closed. Less than 3km up the road, Hollybush Primary School was open as usual.
Shops here moved swiftly to implement social distancing measures with glass barriers erected for staff, hand sanitiser at the door, and the number of safe steps marked out between shoppers on the floor. Going into a shop in the North, you'd have encountered none of this. If you had access to hand sanitiser, it was because you'd brought it with you.
Northern Ireland's policy of not closing schools despite the worsening crisis was challenged at a meeting of the power-sharing executive at Stormont before Johnson moved to close them all.
While Sinn Féin and SDLP ministers at the Stormont Assembly wanted to immediately shut schools, the DUP and Ulster Unionist ministers said they were backing the UK medical advice to keep them open for the time being. The usual politics in the North applied.
The lack of direction from the UK government meant that in cities like Derry it was at the discretion of businesses in the hospitality and entertainment sector whether to stay open or not. Many pubs and cafés took the decision to close. Others did not. It was not an across-the-board unilateral decision and the resulting fallout has been that people in the North were confused about how seriously they should be taking it.
It's clear that in this vacuum, scenes like those we witnessed at the weekend, where beach car parks across Donegal were full, unfolded.
While the UK's new lockdown has now put in place serious restrictions on social gatherings, the lack of clear direction up to now has meant a stark difference in approach on both sides of the Border.
What we have in effect now is more drastic rules to combat Covid-19 in the North compared to the Republic, once again leaving the two jurisdictions out of sync.
Questions are arising now as to how measures will be enforced? Will people travelling from the Republic to work in the North be stopped crossing the Border?
While many cross-border workers - those who worked in the education sector, for example - were already home because of closures, many others are still crossing the Border for work every day.
While the threat of Brexit meltdown - which hung over people's heads in Border communities for so long - has abated for now, a new challenge has emerged that threatens to set things back further.
It has the power to change relations and push people back to a time of suspicion. It's called fear and lack of political leadership across the UK has done a great job of breeding it.
