There is a very good weekend event coming up, the Winter Camping Symposium - October 22-24, 2010 - YMCA Camp Miller (Sturgeon Lake, MN), that is focused on winter camping (doh!).
HERE is a link to the website for the event.
Last year Stairguy was the only hammock hanger to actually camp overnight for the event, though I attended during the day on Saturday only. This year, he and I are muttering seriously about camping on both Friday and Saturday nights. I'm posting this early with the hope that any winter camping wannabe's (me included) can make plans to be there.
Check it out!
