I plan on getting some this year!
I looked all over the internet for some for sale and the only ones I found were a pair for like $300 which was too much for me then.
I have been in touch with Richard F. Hoyer and Ryan Hoyer and I got a lot of good/helpful info about them and may get the chance to go Rubber Boa hunting with Richard F. Hoyer!!!!!!!!!!
