In the region of Calabria, Italia, used a bag of dried rice as my tripod. This was around a 5 second exposure if I can remember correctly. From the film days with my Nikon FM 10 using the bulb setting and cable release. During an outing with nearly 10 friends. I always have tried to merge enjoying life and sneaking in some picture taking while hanging out. More recently it's not so subtle so my friends simply tolerate me doing this sort of thing. This was in 2003.
