Up here in the Canadian Rockies, we just get some skis.

Seriously, we build lots in the winter, then go all out during the "flying season". I've got 2  giants to maiden (1 kit on the table,  ARF soon to arrive) and a race truggy to break in as well. If the weather co-operates we get to the park with the 1Kg electrics, some on skis, some without. We do fly indoors at the high school once a week to keep the rust outta the thumbs.
