http://www.sunfast.jp/SHOP/Y-BAG1200C.html I'm wondering if anyone has used the caster bag (wheeled) shown. I can't seem to find any pictures of the inside or a description of how it's compartmentalized. All the sites that stock it are in Japanese. It's a bit of a walk from car to court 3x per week, and carrying all the baddy stuff and drinks for myself+wife is heavy. This might be a nice lazy solution and easier on my back.
