At least in Texas, when the toll road is paid for, the booths come down. Here in Oklahoma, we built toll roads, and they were to become free when paid for. But, wait... OOPS! We "forgot" to fund their maintenance (and fuel tax goes into the general fund), so we'll just have to keep them operating as toll roads. Sorry...
Well, WHY DO THE TOLL ROADS HAVE SO MANY FREAKIN" POTHOLES THEN?!?!? Where's the dadburned money going?
If it looks like a turd, and stinks like a turd, you probably don't have to poke it with a stick to figure out the inside is full of crap.
