Well I used it the last weekend of Sept and hadn't seen a bill. I posted on the Denver Post today and a guy from E-470 sent me a PM. I gave him my plate# and he sent me the bill in a PDF file. He said they mailed it on Oct. 6th. But to their credit, I had forgotten to change my address on my license plates...which I have done but still there's no way the post office can forward something (if they even do any more) in 30 days. I got mine all paid up today and I'm not using it any more. Here's the email for the guy I talked to. Email him and see if he can find it.
