yeah I know, it's bothersome to bring along tripod to everywhere.

But what I usually did during night shots, I just put my camera on any strong sturdy structure.

Btw, recently I bought a so called 'gorilla flexible tripod' (I called it that way) because it's flexible and quite sturdy, U can bend its legs to any degrees as u like and it weigh just about maybe 250grms. It's also handy n shorty like 15cm in length. I can just put it in my handbag.
