yup, I am the same way, I have been knowned to take people to my house and work on their junk for free just because I could help.
And that person you passed on the trail you didn't help may pass you and not help when you are in trouble. What comes around goes around.
That's why I set myself up with as much stuff as I can cause I am more prepared to help myself and others if needed.
Way to go Marlin.
