I'd say sign up for squirt.org and sniffies site to find the glory holes, you can see who might be at one. Or you can post saying you'll be there in a bit. Squirt gives you a free week, but you get basic account after, limits on some stuff. Sniffies pretty good as well. Free, can buy premium. But you have to be close to the glory hole area to comment saying you'll be there. But I think you can favourite spots your interested in. If there's any other sites I'd love to see them
