This store has a pretty good selection of gear and a lot of clothes (if a bit pricey). If you need long johns or a sleeping bag you can often start here but its bread and butter are from clothing sales, school backpacks and the like for the local college community.
If you get lucky you may be there at the same time as a knowledgeable person, but don't expect any kind of technical knowledge from the all of the staff including where things are or what kind of products they carry, much less how to use things or put stuff together. To be fair, they do carry a useful assortment of odds and ends (bungee cord, webbing/screen etc. by the foot, a modest selection of buckles/cord locks etc.).
I go here if I need something in a real hurry, otherwise I go online since it's always a crap shoot whether they have a specific items, can find them, or know anything about them.
On the internet there are no blank stares...
