Out of curiosity for the car photographers out there, do you contact the security/management of a building if you intend to do a car shoot at their location?
I've done some shots up top of the Impark lot by 7th ave/2nd st SW but this was just by myself.
Also, the Chinook meets, does the organizer pay to set a meet at that parking lot or not?
What if there's 6-8 of you and 2-3 cars?
