We had snow, but not a lot. So hiking to these cache was pretty easy. My plan at the time was to publish these cache while I was vacationing in Florida. Well, I barely was to fly to Florida due to a huge snow storm. 3 plus feet fell in the area. So I put it off for awhile. Well, that was a mistake as fell, hurt myself and screwed up my life but good for a few months
You are hunting for HCH containers. The hides should be winter friendly. Snowshoes could needed. For most caches, a snowmobile can be used(in the winter of course).
Good luck and good caching!
