How do you hide a motorcycle from wife?

You've got to make sure you can access the money to purchase a bike without your wife finding out first and foremost. A bike you have to finance is going to very difficult to hide. You don't want correspondence from lien-holder coming to your home. Also along those lines you don't want insurance or registration/licensing paperwork mailed to your home either. So, you'll need to figure out if you can have all mailings delivered to your office or a nearby friend. Once you're sure you can cover the paper trail you'll have to figure out where to garage the bike. Obviously if you work someplace that has secure storage you have access to all the time would be ideal. The next best solution is a nearby, good friend who's single. I bring up his marital status because chances are if he's married his wife is at least acquainted well enough with your wife to feel the need to rat you out. Oh, and once you find a spot for storage make sure there is room to keep your gear there as well.
