The casino isn't an Indian casino... It's just a casino in Indiana. :-)
It wasn't in a parking garage, it was at the end of a big parking lot... I parked at the end trying to avoid door dings. Unfortunately, the casino says their camera caught nothing.
And yes, I've heard lots of stories about staying away from Anderson. Unfortunately, Shelbyville is twice as far away.
(For those of you not from Indiana, here is the lowdown on Anderson... One of the MTV Teen Moms is from there, and although it's a small town, since this has happened, people have come out of the woodwork telling me about the time they got robbed, vandalized, hit by a drunk driver, etc. etc. when they were in Anderson.)
My guess is removing the straps and cutting the fuel line takes only a few minutes... AND it looks a lot less suspicious to the parking lot security guard to say "Yeah, we're just having car troubles" than it is to be standing there with a siphon hose!
In either case, I need to figure out a way to secure my next tank!
