Question
When does the policy start for a bicycle kept in the hall?
Cover for a bicycle kept in the hall starts on the date the schedule names, and for something newly bought on the day it is added. Adding it is one message to the general mailbox, and a reissued schedule follows.
A bicycle in a communal hall is in the home and not quite in it, and the schedule says which of the two the policy treats it as.
The frame number is stamped under the bottom bracket. It is the detail that makes a bicycle a specific bicycle.
