If interested you call the instructor directly now. 410-474-1517.
He advised me that, yes, the course must be retaken every 3 years and that they are booked though August. I don't really mind doing it, but I think it's BS. Plus all it takes is one little screw up and you lose the card. Lets face it they don't really care about contractors enough to let us use all the facilities so why do they care if we can ride worth a crap? He even said I needed the advanced course since I had already been through the advanced.
Anyway there's a phone#.
That's all I started out to post.
