Here's a couple more questions for the SMART guys. First, how many balls are "normally" loaded into a crate? I'm guessing between 20 and 30. How would things be effected if the crates were a little shorter? It appears the crates could be one or two (...) (20 years ago, 13-Oct-04, to lugnet.org.us.smart)
