Thanx for the compliments.
It's pretty much free standing. I wrapped the base in such a way as to sit level. There are basically just a couple oversized steel "tent" stakes holding it to the ground.
I didn't wanna cement it in, due to "break away" laws. If a car hits it, it has to be able to give. Last thing I need it to be sued because someone runs into it and breaks a nail, or something equally retarded.
