For that funny super-sticky clear tape you need to fix a tear in a tent ("Tenacious tape"), for tubes of seam sealer or replacement buckles for your webbing, that spare hank of no-see-um netting—all those little niggling emergency camping items you really wish you had when you don't have them—REI has the best selection. Of course, you have to be careful you don't fall prey to REI disease and accidentally buy a tent or something when you go in there. The store is in a spot on LBJ that just seems harder to get to the more construction they do in the vicinity. Best plan is to get off LBJ at Dallas North Tollway and try to find your way westbound on the LBJ service drive. REI is between the Guitar Center and Haverty's. But stay off that cell phone or you'll wind up in Coppell, and somebody might sell you a whole house.
