I've personally never been to Blackfoot River Outfitters but their gear swap sounds like a pretty good deal.

The 'Fly Fishing Gear Swap & Skwalapalooza' is this Saturday, March 5th at BRO (for short) from 9 a.m. to 3 p.m. They will also have a $500 Simms shopping spree and Orvis give aways up for grabs. Plus, 20% off sales and hands on gear demos from reps.

BRO invites you to bring your own used gear for store credit or cash. They are at 3055 North Reserve, across from Lowe's.
