One of the best gadgets in my photography toolbox for my photo-walks is something called a Platypod. It is the world's most compact tripod base.
Years ago, I remember traveling to Washington DC to photograph the Capitol Building at sunset. I was shocked when a security officer informed me that tripods are banned. I also encounter the same situation on top of the Rockefeller Center observatory in NYC.
Even though it is a hassle, I used to carry my tripod on my motorcycle rides all the time. Now I use a Platypod. In my opinion, Platypod is a game changer for travel photography. No need to carry heavy tripods. It is all about traveling light and having fun. Check it out, it is a great tool.
