Hey there, I live in maine and have been riding (legally, I hope!) for over a decade. I am still learning wiki but it looks like you updated the maine entry to show a 9$ moped registration fee.
do you have a link to this? for one, I may be paying too much as some of my 50cc bikes fetch 45$ at city hall---
also for accuracy, I don't think I've heard of a "one-stop 9$ fee"
let me know, maybe a link to your info, thanks a bunch, let me know what you think.
