On a weekly basis, it might be. Hell, try navigating around my neighborhood during the summer when every other house is doing a yard sale and all the people are parked in the friggin road. It's not just an inconvenience, it's UNSAFE.
Frankly, the whole issue is with the City Code, in this case, section 9-3.301 of the Capistrano Municipal Code, which prohibits "religious, fraternal or non-profit" organizations in residential neighborhoods without a conditional-use permit. Money-grubbing? Maybe, but it might also be about getting access for fire/police were an emergency to occur.
The city has stated that the issue was never about religious freedom, but rather about parking and street access. I would tend to agree.
If they feel the law is unjust, then work to change it, but of course, America has become such a litiguous nation that we'll sue every time we get butt-hurt. Evidently, the code enforcement folks thought there was an issue, or else they wouldn't have issued warnings and/or citations.
Sorry folks, but I've got to take the side of the city on this one. It's not a 1A issue. Of course, I wish the Fromms all the best and hope they do get the law changed or at least reduced in scope. 2000 people at your house is a bit much, but 20 is certainly reasonable.
