I want to build a hotwheel parking garage for my sons. We have a train table that is perfec as a play table, and was going to build a multi-level garage for him to play with. The wife vetoed that, but found one that she likes (oddly, its exactly what I would have built, only smaller). Its $100 freaking dollars. Please help me find a bigger, better, badder parking garage for my boys to play with.
