Good place to gather and march from.

750 could easily block all doors symbolically, also possible provo action: detour Lake shore drive traffic into immediate neighborhood with wooden horses, etc, then stop cars with other wooden horses, then saturate with people. then let air out of tires of more and more coars until tanks, etc in armory can't get out. A few cars sacrificed for most direct blocking of garage doors. Aluminum door could be bent o out of operation. Could NWU form a sanctuary? Source of cadre?

Lots of fire hydrants for further confusion, first aid for gas attacks Construction site(s) would provide barricade materials. Apartment houses and hotels provide many blind alleys, which connect, for possible escape through confusion.
