The demoncRATS built a 4 mile fence around the convention center in Philly!!  But it ain't keeping out drugs and non Americans it is keeping American citizens out...............this convention is a members only plantation,  and these members are the demoncRAT masters.

Good video of the fence on periscope,  some jail fences aren't this well built,  I estimate the rent at 4miles which is 21,120 ftX $100/ft = $2million (materials) + labor 200 guys @ $25/hr for 2weeks 80 hrs 200 x 25 x80 = $400,000 so this thing give or take cost a couple million bucks.
