If you ever get lost and you look over and see the world's largest anything, chances are you're in Houston. Fishing Tackle Unlimited helps with that, because the place is literally the world's largest tackle store. The good thing is, it's not an overdone Disney World-type place like other mammoth outdoor shops. The reel section alone is enough to make your head spin — especially if you check out the price tags. You can also "test drive" kayaks in the store's outdoor pool. Put it this way: If you're working on a research paper about fishing, skip the library and head to Fishing Tackle Unlimited, just south of Hobby before Clear Lake.
