I was down on 8th street the other night picking up my hunan chicken combo from China Wall when I passed by a dentist's office. The office was closed but there was a group of about a dozen people huddled out front. The people in the group were all in their mid-forties and dressed in expensive looking fleece jackets and cargo pants. Also, they were all carrying sleeping bags and pillows in their arms.
I passed by the group and went into China Wall to pick up my order. On the way out the group had unlocked the front door to the dentist's office and were all filing inside.
I have no idea what that was about.
