Matt, You should have all the info on the location and contact info, I found for last year's rally.
The spot you all picked was a bit east of what I was thinking...I thought if you moved all the way to the West side of that parking lot, you could hang banners behind trucks or set up your tent in the far west corner, so the Rising Sun banners could be seen from hwy 95 traffic.
Another idea is to host it in a corner of a Bass or Cabella's parking lot. That would be a cool location.
Also is there a lot near Big Choice that might work??
Just some thoughts here, good luck with planning this year, I am sure it will be great! One of my favorite events to attend.
