Check out the USB powered ones. They'll be easier to power with just a normal battery bank.

I grew up in Oregon, but they went soo crazy I decided to move back to America about 3 years ago. Seen several shows, but not Oak Ridge Boys yet. Caught a couple Bass, and Got my first 4 Deer since moving.
We've done the fantastic caverns several times, but I haven't done the marvel one. We've also seen several shows (I get in free because I work at branson.com selling tickets to them.)
I've been to SDC and rode several roller coasters, but there were a couple out of commission and I don't remember the names of them. Great times though.
