Texas went to straight cameras on the pikes (eastern term) but Houston gave in and put 'cashboxes' on Beltway8. Cashbox referring to a body in a box with change and receipts for the working folks. Or a fishnet to catch the change thrown at it, chuckl. Flyway refers to nonstop. Sunpikes (Florida) tollroads, turnpikes, I forget all the terms used. They tag your license plate and mail to you. You CAN fight the charges. We have a Harley in the garage that doesnt move, but Tollroad Authority occasionally sends us a bill for a black picture of a lic plate on it every so often. Mostly online access
