How do you guys go about shipping large or heavy items? I have to ship 4 wheels w/tires from Wisconsin to California, and I'd like to get them there damage free. Each weighs about 75 lbs. I was thinking along the lines of a wooden crate, for sturdiness. Any help is appreciated! Dave Hiller 90 K-5 87 K-5, 84 K-15, 96 9c1 - Please don't slow down in front of me!
