what a stupid thing to do

Experience sometimes trumps schooling.

This is one of the comments I made to my brother the other day.
"This up coming generation could tell you all about it, but can't actually do it."

Not to belittle your Son's education, as I used to have all those same certs as well as ATRA (automatic trans builders Assoc) but there are times when experience is worth more than all the schooling available.

At least you know from experience. :D
