I've just moved in my with girlfrend to a two bedroom apartment and am curious as to how to store my bikes in this place. The second room is our workout room (AWESOME) but I won't be able to store my/our bikes in there as there won't be room. We've got 2 road bikes, my tri bike and my mountain bike to find room for... this wasn't a problem with mom and dad's big ole house but all of a sudden space is a little less available. There is room on a wall to store 'em standing upright, is this the best option, and if so, are the hooks that are sold for that purpose necessary, or can I just go to home depot and pick up some big old hooks for 1/10 the price?

Anyone with some brilliant ideas?
