Apparently the evictions in St. Louis touched a nerve in Pittsburgh as several actions were reported to pghanarchy.tumblr.com:
NEW SQUAT OPENED
Hearing of the eviction notices in St. Louis, some anarchists decided to act in solidarity by opening a new squat in Pittsburgh. Somewhere in the hills we entered the house we have been casing out, tidied up a bit, and put new locks on the door. At least a few comrades plan on moving in soon.
