I think planning for Spring makes sense. That way people have time to arrange their work schedules, etc. This autumn would've been great (with the fall colors, crisp air - ahhhh! ), but it's too soon. Also, as Iowa said, there's the chance of freezing temps, poor travel conditions and possibly even snow in your tent - depending on where we all choose to go!

I can tell you that Colorado has some spectacular places to camp and - it being my backyard - I'd be happy to organize things if it is chosen. Take a peek at some of KOA's Colorado locations - most are quite nice...
