I would be more than glad to help someone passing through my area, so you could put me in the booklet.
And Cletis is right, might pm those along your route and see if you broke down if they could help.
About 4 years ago I (with my family in tow) broke down in the middle of Oklahoma, and didn't know a soul to call for help. Luckily a nephew was about an hour ahead of me going to the same destination. Finally got in touch with him and he came back and helped.
So having something with contact numbers would be helpful on a trip.
