If you have any verticle elevation around you, maybe look into snow boards....also wake boards are a huge hit right now.
Any business can work, but it takes tremendous dedication. Especially in a one store retail outfit. Don't let that scare you, but be prepared for 80 hour weeks at times when you are starting out. If it is something you really want to do, get yourself together a good plan and go for it.
Find a good attorney, accountant and banker. You will need all 3
Good luck, have fun!!
