Carry a 2M HT and hit the local repeater when you break down. Give them your position and they'll call a tow truck for you.

This is why I come here, for the practical solutions to problems.

Could you elaborate on this a bit more? What's a local repeater? How do I 'hit it', so to speak, etc?

I don't drive :).

I do not own a TV proper. I own a Sony HMZ-T1 instead.
