We do have seasons, just a little bit different:
Breakup - that time when the snow is mushy and you can't really ride very much unless you haul everything 200 miles away to the mountains.
Summer - June and July, the sunlight is always there and so are the mosquitos. No darkness at all...except when the smoke from forest fires cover the sun. Right now it is 77 degrees outside. (June 17th). The sun sets for about 2 hours, but it never gets dark until August. August is a 50/50 chance of either being to wet to do anything fun or/and just everyone saving up for hunting season.
Hunting Season - Only last a few weeks, everyone has worked on their boats and 4 wheelers prepping for this 2 weeks.
The boring time - Two cold to do anything outside, but no snow yet (Sept-Oct).
First snow time - Not really deep enough to ride, but some people do. Specially fanners and small machines (old Tundra/Bravos), but water is still not frozen so limited access
Thanksgiving - Kind of marks the first time anyone dares to go across the lakes. After the first person makes it, then others will ice-fish and we learn the true thickness of the ice.
Some years we have lots of snow, other years we have no snow yet.
Darkness - Nov-Dec-Jan-Feb are dark. Sun rises for about 2 hours in Dec and even then it is just barely up. Most riding is in the dark, of course. However, these are also the coldest months and by coldest, I mean -20F and colder for a good portion of them.
March-April - Prime riding season. Warmer, more light, and typically all the snow we'll get for the year.
