We were stopped at one of the oasis rest stops in Illinois for ice cream, on a hot summer day in 1999.  We were on our way to a show at Madison or alpine or somewhere. When i was on my way back to my car, i noticed someone messing around under it, then leaving a note on my windshield, then hopping in their car and driving away. 

I was kinda worried, since strangers hanging around your car at rest stops is usually a bad thing. But what did i find when i got to my car? The note said, "You're losing coolant fast. I left some under your car. See you at the show!" There was a brand new big jug of coolant under my car, sure enough, the kind that cost ten dollars. I checked my coolant, and I would not have noticed that it was completely empty unless this awesome head had let me know! 

We made it to the show because of this kind someone. So thanks, man.
