Nearly all the B&B's I've stayed at along the GAP and the C&O have an indoor location to store your hikes overnight. I've actually taken my bike indoor at those few hotels I've stayed, particularly in Cumberland and Leesburg. I admit to not locking my bike at restaurants and inns away from the larger cities and have not had anything taken.
Howeve, I've finally conceded to take along a light cable lock when my bike is not within site when I leave it. It's just not worth, what I believe, is even a small risk. I have had a bike stolen at a coffee shop in downtown Pittsburgh and it's truly a sinking feeling but, at least, I wasn't far from home and not hundreds of mile down the trail.
