Congrats to your grandson and yourself!! He'll enjoy being out with you no matter what he sees or doesn't.
I took mine in '78 and retook it in '90 when I signed up to be an instructor. Figured it couldn't hurt, and yes the records the state
has kept until around 1990 were pretty bad. Instructors kept for 10 years and then they would throw them out.
My original instructor had passed away, and the state didn't even know.....
Guess they thought he just wasn't giving classes anymore....
