From the catalog description: "Indoors or out, our inflatable games are perfect for parties or afternoon play. The bowling game includes three 42-inch-tall pins and a ball (25-inch diameter). Made of extra-durable, water-resistant PVC."
Now, if they'd just add a 60-inch-tall pitcher of cold draft beer ... (not so good for kids, I guess).
Next to homebrewing, this could be the ultimate DIY project: building a bowling alley in your garage. The guy is identified by TechEBlog as "Tim W.," with no reference as to where he lives. (I'm guessing it's the Midwest.)
The Brunswick automatic pinsetter is a noisy beast, and the lane is short (although probably about the same as the duckpin lanes at Koz's Mini Bowl in Milwaukee). But it's pretty darn cool to have a lane like that in your garage. Wonder if there's a Kegerator hiding off to the side somewhere?
