I would walk away. Not only is he super young, but his reply was less than intelligent. I don't know about you, but improper spelling and grammar makes me run for the hills.
Me too. I can understand a typo here and there, but when I first saw his post on Craigslist, I questioned his age. I'm not running with this idea and definitely looking elsewhere. Another thing I can't understand why his parents would allow him to do this? Can't he or his parents be held accountable in a lawsuit or would this be more of a "ride at your own risk with an uncertified instructor" sort of deal?
