Buckman,
Anyone who mates has to be enrolled in some drug testing program

I would 1st suggest doing this and whoever's boat you are looking to mate on, that will look favorable for you.
As for me being mentioned, I'm not sure I'm in need now, but things could change and I will keep you in mind.
If you are down in Dennis, I'm pretty sure there are many options in Bass river or Chatham.
