Bill’s Place is a biker bar that tolerates non-motorized bikers. The food is good and reasonably priced. Never had an issue there, but did not stop in on my last trip, as I had already eaten. Rumor last year was they are closing, but that is unconfirmed. The C&O mosquitoes are something else. With the 185 mile long breeding pond next to the towpath on the one side and the river on the other, you’ll have plenty of company. You can always hop off the canal in Cabin John at Lock 8 if you need a bite to eat. Several restaurants and stores along the way.
