RAGBRAI .. I've never done it, might this summer.. looking for info

I'm trying to figure out a tour.. so, last night I was doing the look
at places I've never bicycled at, and the RAGBRAI ride popped up.

I got to wondering ... somehow get to the start, ride the ride,, across
Iowa,
then keep on trucking back to New England for a kinda almost across the
country ride..

What do ya think?

How do ya get to the start of RAGBRAI?

How much? Where do I get a bib?

Any and all thoughts?

Thanks...
