The few times I went into either of the PB shops, they were totally void of customers and I always wondered what kept them open. I had no bad experience with them, just couldn't figure out how they stayed in business with no customers.
While we're on the subject about bike shops. Another shop that I never heard talked about is Bucks Bikes. I've been in the shop on 183 a few times and the same thing, the place was empty. No bad experience for me, it's just always made me wonder since I never hear anyone mention them.
