Bordon811, You might consider going to the local Wally World, or similar store and trying to find a small 'beach' umbrella for some temporary shade...This is what I use on a PD shoot... Not the best, but it works and was cheap...I use a couple of plastic electrical ties to stabilize it to my portable shooting bench...
While it's not "camo'd", the PDs don't care and we go to a private ranches where other shooters are not allowed, but if someone sneaks in, it makes it easier to be seen...
