Ice castles become tourist attractions
Farming is tough in New Hampshire in the winter - unless you are growing icicles.
That is what is happening at Loon Mountain in Lincoln, where thousands of icicles have been grown, picked and assembled to create an ice castle not unlike the palace in the Disney movie Frozen.
It is one of three ice castles being built this winter - the others are in Breckinridge, Colorado, and Midway, Utah.
Brent Christensen started his Ice Castles company a few years ago after building elaborate slides and ice towers for his children in his Utah garden.
The construction process involves spraying water on to metal racks to produce icicles that are stuck to the ground around sprinkler heads. After a few weeks, towers, tunnels, archways and caves emerge.
