DIY Dolly

In his memoir, Allen Baron mentions that in filming Blast of Silence, they used a dolly consisting of wheels that attached to the base of the tripod. I used this same type of dolly when I shot Unknown Number. The trick, of course, is stabilizing the movement when you have the wheels but no track to run them on. Well, Baron and his crew came up with a good solution to that: throwing a 100-pound sack of sand across the base of the dolly to help keep it steady!

Wish I'd thought of that...
