Greysmom gave you some great sources for muzzles. My greys came with muzzles from the track, but I have also purchased some at the GEM store. In the meantime, some of us have extra muzzles in our cars until you get yours. When I get your email address I can add you to the distribution list for info about meetings times each week. Next Saturday we will be meeting at 7:15. Just flag one of us down before entering the enclosed park area and we can let you borrow one of our muzzles for the hour that we meet that day.
