Hello GDietz
Welcome to MV, yeah there are alot of abriviations... go to the link provided by Danny*h. There are alot of good folks here as well as the few cranky ones... but then who doesn't get a little cranky now and then.
Sounds like you have two great scoots, and that you have had them for a while. When you figure out how, please post a picture of them, we all like to see the pictures of the scoots others ride... dings, scratches or pure un-marred beauty. Doesn't matter if we have seen 100 of the same scoot, these are your scoots.
Wow you live in the whole United States.. I have trouble just managing to live in the N-California area....

When you feel more comfortable please let us know the general area you live in. Some here have no other scooters in their area and would love to know there is someone else near by. Others like myself just like to know someone else who rides in the area so you can be invited to some group rides.
Hope to see some pictures of the scoots soon, enjoy the ride every chance you get, and if you do not get many invent them...
