Portland and vicinity
I just relocated again... this time to Portland area. I'm completely out of shape. Haven't ridden in MONTHS. Any nice, flat routes you can recommend? Any slower-paced social groups out there?
The nice thing about Portland is you have such a wide variety of rides... you can make them as flat or as hilly as you like. There's a MUP that parallels Marine View Drive along the Columbia River, it's a pleasant flat cruise with great views of Mount Hood, St. Helens, and of course the river. It can get windy, though. Other flat rides include the paths along either side of the Willamette River downtown, and the Springwater rail to trail path southeast of there. I don't live there (too bad) so I can't advise you on local riding groups.
Check out http://www.rubbertotheroad.com/, it's the website companion to the eponymous book which describes several rides of varying difficulty in the Portland metro area.
Also google Springwater Corridor for info on that MUP.
They have a variety of groups depending on your speed.
