I've got two of a very similar design, which I will bring along with two IDPA cardboards and some firring strips. If need be, one can drive the firring strips directly into the ground with a hammer, staple the cardboard and run as is.
I am probably going to pitch camp on the 50 yard range to start, just because this is a group of AR enthusiasts so it would be ironic to stick to the handguns only 25 range.
I have a small rifle rack, but I will try to make a larger one tomorrow, just in case. Won't be fancy.
