I felt anxious when I first went into my LBS, but they've turned out to be incredibly friendly and supportive. I sometimes get curious looks from other customers, but they're not hostile.
There are enough cyclists here (mostly roadie types, but some commuters) that I often cross paths with someone on my rides, and I usually get a smile and nod. One woman actually slowed down to ride beside me and chat for a bit, for a few hundred yards.
Unfortunately those rides have been few and far between lately, and I haven't been able to brag to the LBS guys about losing another 10 pounds... so... time to get back at it.
