Jim - glad to hear the "tosser" is back in good shape. Have you ever tried one of those little portable 3 legged stools? I have one and I love it. It's called a WalkStool. It is very light weight, collapses to 14" and has it's own bag that easily attaches to my backpack or takes up very little room in my big camera bag. The one I have is 18" tall and is rated at 440#. It gets me low enough to get the shots I want and even with my bad knees, allows me to get up with ease. I always take it to shows to sit ringside for candids cause it gets me lower than a regular chair and I can move it around easily. They have a couple of other models that are 22" and 26" with higher weight capacities and bigger seats, but I find the 18" to be just perfect.
