Dude, don't let me hear any of that cancelling stuff!

YOU'RE GOING!
According to my calculations, it will take 3-4 tanks of juice to get there, and 3-4 tanks to get back. Its 750 miles each way, and if you get 250 miles per tank, that's 6 tanks round trip. I would throw in a few extra tanks depending on how much driving you do while we are there.
You can always bring a length of tubing so you can syphon gas from other peoples' cars too.

JK. I'm glad we have locking gas caps.

EDIT: Its actually only 700 miles going on 50, that 750 miles was if we take I-80, which we are not, so that's even less. We should definitely make it there is 3 tanks.
