That sounds like a really great idea! A nice scenic fall colors loop, and maybe close enough to all our MIA Tacoma members to rouse them out of hiding.
I have personal interest since I've lived in WA 30 years, been an avid hiker and sight seer, and yet I've never been that close to Mt. Rainier!
So I give a thumbs up to the idea, with a few concerns: a) I have no idea where pretty much any of those places are (including the starting point) so good directions and maps would have to be made. b) when does it start snowing around there? Would we be snow-free if we scheduled for October?
