Not that I'm aware of. I guess you could call a friend who is there and have them bid for you. The best part is that you get to try hundreds of calls from the best makers out there. I was surprised at how good some of the calls were and surprised that some of the big names out there were not as good as i expected. I never played a Bill Lyman, Clint Corder or Kimmy hanks call before but to my ears every call they had there sounded great. Some call makers had one surface that was really good and others that were so so but these guys had everyone nailed. Schaeffer and Platz had some great ones as well and I only mention them second because I already have a bunch of calls from those guys and added a few more while I was there. Anyway, there were a bunch of other pot calls there that were great too but the list would go on and on.
For box calls, which I don't use as much, Frank Kruer's sounded really good. I have one on order since playing them there. Again, bunch if others but his stood out to me.
