Pressure depends a lot on the available public land in the area you are hunting. If there is little to none, the WIA's get hammered. If there is significant public land, then WIA's might not see as much pressure. Whatever the case, the program is great. Always donate a little toward them when you buy a license and abide by the few simple rules that they have. The G&F works with landowners to get access, and the landowners can take that access away anytime. Remember that you are on a private ranch, essentially for free, and that it is pretty cool.
