Low-fuel trip idea

Ooh, I just found a cool idea for a week-long trip: Bike the C&O canal up from Washington DC to Cumberland, Maryland. It's a 185-mile trek right along the Potomac River. I could have one of my brothers drop me and my bike off in downtown DC- rattle off 35-40 miles a day - and get a pickup in Cumberland after 5 days. I'll have to plan out details (where to stop overnight and carry-on gear for my old mountain bike,) but I already have all the camping gear I'd need. Sounds a lot neater than my typical "run yet another mountain ridge" weekend hike. I probably couldn't find the spare time to do it until this fall, but that'd give me plenty of time to train up and prepare. I'll have to look into it a little more this weekend.
