Crawlers would be a great idea, a little tougher and much slower. I suppose a Slash wouldn't hurt either.

As for the radio waves, then yes I would bring all three types of our radios. AM FM and 2.4, maybe a household wireless phone @ a higher wavelength, etc. I can't remember what cell phones operate off of but I know it is up there as well.
