Jason you sound like a nice young man. Plus your are going to purdue which both my parents attended. Your are right dont let anyone discourage you.Plus I was raised in your area.I know what you are up against. I grew up in park ridge and worked at medinah golf course near you.Dont take offense for anyone giving you advice.Hope you have a great summer working. But do yourself a favor you are too old not to do it legit .Get a license,insurance.Jason you are not 16 no more.
