## About this plate

Two things worth carrying forward. First, Colorado's programme is STATUTE-SHAPED in a way Florida's is not: the rulemaking route closed on 1 January 2001, so the catalogue is literally a list of sections of Title 42, and a future pass can enumerate it from the code rather than from a web page. Second, the three-thousand- signature gate plus the three-thousand-vehicle retirement threshold make Colorado's index unusually STABLE, programmes here are expensive to create and mechanically pruned, which is the opposite of the churn Florida records.

## About the format

It is emphatically NOT the claim that a matching string is a valid Colorado group-special serial.
