Fogdog Outdoor Store I am truely amazed at the selection of camping and backpacking gear this place has. Also carries the sometimes-hard-to-find Coleman non-stick griddle, which you'll use with your Weber Go-Anywhere Grill (both are must-have items that we learned about from the Yales. Thanks, Dave!).
Amazon Would a collection of links be complete without Amazon? Hell no! We buy tons of stuff from these guys: books on every topic you can imagine, CDs, videos, tools, games, Palm PDAs, and most importantly, the Weber Go-Anywhere Grill.
Cabelas Bunch o' stuff for huntin', fishin', and campin'. Bought lots o' stuff there myself.
Campmor Who hasn't bought their first set of real backpacking equipment from Campmor? Tons of stuff for all types of outdoor activities.
Northern Mountain Supply This is a great site with lots o' gear and killer deals. I bought my Dana Design Longbed backpack at a killer price from these guys. Good help, good prices, fast delivery, what else can I say?
