Durianrider and Freelea are apparently touring around the U.S. and will be speaking at Arnold's Way in Lansdale, PA on August 1st. Attendance cost $10. Check out their flyer here.
Arnold's Way is an excellent raw vegan cafe and the talk is sure to be worthwhile.
The address is: 319 West Main Street, Lansdale, PA.
If you live in Philadelphia, it is very easy to get to via public transportation. Just ride the Lansdale/Doylestown line from Suburban Station north to Lansdale, which is 12 stops. On August 1st, taking the 5:20pm train will get you there at 6:15pm. Arnold's Way is literally right across the street from the train station in Lansdale. Check out rail directions here.
