Ron, That access panel is going to be a burr under your saddle for years. There's far more wrong with USGS than just that, and then don't get me started on Specs and Tech. Maybe this discussion should be on sprinkler chat so we can get way off topic if we want and then bring the meat onto the Forum for discussion. I think there's some real general pros as well as cons with all this gov'ment stuff and would certainly like to play.
