Nice score! Once cleaned up a bit it'll look great. I hope you plan on keeping it.
I picked up my Rolling Rock(my first cruiser) from a lady that sells stolen/lost/recovered bicycles for her local police department. Every inch of chrome was peppered with rust and the tank was dented on one side. It cleaned up great and the dent popped out pretty good. It's an awesome looking and riding bike.
At the time I got my Rolling Rock I had been lurking on RRB for a few months, but didn't even have a bike yet. I was 35 last year when I got it, but that cold, wet, fall day that I picked it up made me feel like it was Christmas and I was 12 years old. It was the bike that started it all for me. 8)
