Open one with an outdoor range!! My favorite shop in the world is Carl's Golfland in Michigan (either location). I spend a few hours there every time I go home to visit family. Both have big ranges and they give you a demo bucket to try clubs out. The plymouth one has a 400 yard double ended range where you hit back towards each other. For a putting area, I think it would be cool to have putting "bays" or strips of good quality fake turf about 3 feet wide and 15 feet long. It's annoying when you're trying out a putter and a bunch of kids are running around smacking balls while their parents shop. If you go
here, you can see a pic of a corner of their plymouth location.
