I was sleeping in my vehicle at a rest stop on I-75 (probably Kentucky, maybe Tenessee), when my 5-yo SchH3 dog told me in no uncertain terms that somebody was outside, and was up to no good. Some guy said he wanted me to get out of my minivan at 3AM in November to help him fix the timing belt on his car. I told him there was a phone in the building and drove for a while longer before stopping for more sleep.
