Some want rid of direct payments and the farms that depend on them, which they view as inefficient and a drag on the industry.
I distinctly remember one Leave supporter saying "subsidised old codgers" were blocking new entrants and fresh ideas. Others, particularly in the arable areas, hope a Brexit will mean the relaxation of the precautionary principle and better access to new crop protection products, and maybe even GMOs. But if anyone thought for a minute these things would happen quickly - if ever - they are very much mistaken.
Britain is still reeling from the shock. No one, not even those who voted to leave the EU, can quite believe it's actually happening.
The National Farmers' Union is making the best of it by calling on farmers to take control of their destiny.
This month they are launching the biggest consultation for a generation.
NFU bosses have agreed on a set of core principles, which could form the basis of a new domestic agricultural policy, or at least what the NFU wants from one.
Meetings will be held all over the UK to discuss the pros and cons.
They hope to have it signed off and ready to deliver to government by October.
The NFU cannot be accused of acting slowly. Less than a month after the referendum result, the four presidents, representing each nation, met in Brussels to set out their priorities.
England put access to European markets and new global trade agreements at the top of its list, Scotland stressed the importance of access to labour, Wales called for a science-based approach to pesticides and herbicides and Northern Ireland a removal of costly bureaucracy.
Some of it tallies with what our new Defra Secretary of State Andrea Leadsom said in a letter to the Farmers' Weekly exactly a month after the referendum.
In it she appears very positive, ambitious even, about trade and export opportunities and recognises the £100bn a year contribution to the economy from food and farming.
But she makes no mention of continued support payments for farmers after we leave the EU, and I was surprised none of the four NFU leaders mentioned it at the earliest opportunity either.
This will be something to watch very closely.
My Dad, a sheep and beef producer and a staunch Remainer, is disillusioned.
"How can the NFU represent the interests of the big arable men in the east and the small livestock farmers in the hills at the same time?" he asked.
Personally, I believe now is the time for every British farmer to stand up and have his or her voice heard, to be part of the first British Agricultural Policy in decades.
Yes, our industry is fragmented and regionalised but there are strengths in that too. We do a lot of things well - from beef to barley, pork to potatoes, sheep to strawberries. And it's time to shout about it.
Someone suggested to me the other day that Irish farming will far much worse out of Brexit than ours.
I can see their point but with emotions running so high at home, I hope you don't mind if I keep that thought to myself when I get off the ferry at Holyhead.
