i am @ 22485 of VA. i think there is a shop over in maryland. the website is the best i have seen of any shop. new bikes bought there are warranty for life on performance adjustment such as brake, shifter, etc. i am going to try to go there this weekend and buy my tubes. they're been in business for 13 years and southern maryland is very very bike friendly as all highway, even many side road, have a full lane for bike and emergency use. this is probably the best area for long commute as the road is very well paved and there is plenty of space to ride on.

i'll go there and get my tubes to fix my flat to give them some business for starter. then if there service is good i'll pick up a bike from them. they carry a lot of brands.
