Fall is my favorite (sept through mid october). Summer is fine, which around here starts in July. Spring makes me crazy because the roads to the trailheads aren't open, and even if they are the low country is a slushy muddy mess and the high country is still in winter. The raging streams are not crossable, the slopes are avalanche prone, and the snow is no longer fit for x-country skiing. The wind blows 30 mph all day every day. All of this occurs just as the effects of the loooooong winter are starting to make me crazy. Spring is the hardest season to get an outdoor fix. The only solution is to drive south about 10 hours, which I do at every opportunity.
