My never-used Bogen "Roll Pod" is for sale. It's a large-wheeled device for transporting an erected tripod with or without camera and lens attached. The rubber-tired spoked wheels are about 2' in diameter. A typical application might be a zoo shoot, where one could leave a camera and lens, even the biggest of lenses, on the tripod, and easily wheel the entire assembly around the zoo without packing and unpacking at every stop. Zoo trips are but one example. Sporting events also come to mind. The Roll Pod has been in my garage since I acquired it, and while pretty dusty by now, it's never been used - not once. Sold at B&H for $170. and I'll take $100.
