Everyone has their favorite seasonal acitivities. Some, such as skiing/snowboarding, necessarily require the season's weather (e.g. need snow to ski), others because certain institutions conduct activities only during certain seasons (e.g. the State DNR only issues hunting licenses for a specific time or college football is only played in the fall), and yet others take place during certain seasons more or less out of tradition and not because they couldn't occur at other times (e.g. going to cider mills and doing the cider/donuts/hayrides thang). Lastly, there are certain seasonal activities associated with holidays and events tied to the calendar (e.g. cutting down the Christmas tree or getting trashed at Mardi Gras)
