Hi Sid! You need to stop by and get the bike inspected( if over 5 yrs old) at any of the hundreds of shops w a blue and yellow sign that looks like a sprocket. Take your green book. Stop across the street from the dmv and get your govt insurance. Take all that and the book into the dmv.
They probably take debit card or credit cards. Quite sure they would escort you to an atm should the need arise and you dont want to take cash with you.
Ironic you should mention spam.....Mott’s Visa Service spammed me 5 minutes before I read this 5en told me they have “no idea” how this happened as they only message people they know or work with.
