Yes, we did know that it was the same dates as Spyderpalooza and we did our best to schedule around it, however our goal is to have the best event and not necessarily the biggest. To accomplish this we needed certain venues that where already booked on the other weekends in September, so we had no choice but to go with this weekend. I feel that it will not interfere with each other being 1200 miles apart. Good luck with your event. Ron
