I've been in here for 8 years and never thought of the forums having a vastly different "seasonal" volume of posts. I guess if you are in the north and interested in weekend warrior kinda stuff, maybe, but for us in the south and full-timers there is always something to talk about!
In fact, I see the OP is in N. Cal. Turns out I hope to travel up there next summer and will likely be doing planning later this winter and would be looking for locals with input.
