The Marion County Libertarian Party has recently started to send to its activists a reminder postcard of its monthly meeting. This is very helpful and appears to me to be improving attendance at their meetings.
I received my postcard today for the meeting this coming Monday, September 19th. The meeting is held at Shapiro's Delicatessen/Cafeteria near downtown Indianapolis (808 S. Meridian Street). It starts at 7 pm, but get there early and have dinner beforehand.
