thanks, dave. i have been searching and searching but to no avail. i think some tool in my building (locked courtyard requires vestibule keys to get in) saw me taking her out and targeted her, so they probably planned it out and she is probably long gone by now.
i don't think random kids would break into the courtyard and steal my locked, covered moped that is difficult (if not almost impossible for me when all the bikes are there) to get out but leave the four or five bikes that are unlocked there.
i just hope that if i never see her again they take her far enough away where they won't spray paint her so she can still be green and red and yellow and totally awesome.
