Thanks, Chris! Your weights are nice looking, do you use more than one on a corner? I am so paranoid now, I think I'll aim for 40-50 lbs per pole!

I weighed one of my cinder blocks, and it was almost 50 lbs, but not as attractive.
Now I'll just have to find some beefy guys to haul it all around for me. I'm not very muscley myself.
