Start in front of the hare's flat (Birsstrasse 52) - can leave bags there for anyone with the energy to climb the stairs. Easiest directions are to take the #3 tram from Aeschenplatz (8, 10 and 11 from SBB) and get off at Schulstrasse in Birsfelden; cross the Fussgängerbridge and right up Birsstrasse until #52. We can also do the down downs there on the Birs, weather permitting! :)

The On On will most likely be at a restaurant here in Birsfelden.
