TIP: First thing you want to do when you go to REI is buy a Co-op membership. It's only $20 for a LIFETIME membership and it gets you an annual dividend based on how much you spend during the previous year (typically around 10% back), and access to their Garage Sales.
They have a great selection of outdoor gear here. Sure, in some cases the prices may shock you, but you pay for quality and when you're out in the middle of nowhere relying on your gear to keep you warm and safe, you'll be happy that you paid a little extra for the good stuff! They do have less expensive alternatives as well.
Aside from the selection, the one thing that I really appreciate at REI, especially at this location, is their staff. I have always found them to be friendly and knowledgeable. They know the gear and they know what you'll need for your trip, because they've used the gear on all of their own trips.
I've never had a bad experience there and I look forward to more adventures!!
