Hey all, 
I'm totally brand new to this forum and the Pacific Northwest, so please bear with me.... 
  
About 6 years ago, I quit my job in New Hamhpsire, bought a puppy and started driving across the country.  I ran out of money in Wyoming and ended up living high in the Colorado Rockies (Breckenridge area) since then. A mountaineering trip to China I had been planning fell through, so now I've got a couple weeks available this fall for other adventures and I've been thinking about finishing my cross-country trip. 
  
Anybody have any recommendations on where to go, what to do? I'd like to do some backpacking and/or climb some big mountains.  I will have my dog, so I won't be able to do any National Parks with him. I would love to climb Rainier, but what would it be like in October-ish? And yes, I realize Rainier is a National Park, so I'd have to board the pooch for a few days if I do climb it. 
  
Any sweet backpacking trips with solitude, amzing scenery and lakes to do some fly-fishing?  
  
Any help would be appreciated. 
Thanks, 
Colin
