No rain or moisture at all. The poles are about 30'- 40' feet from the wires. The lot lights which are parallel to the lines but further away did give me a "lighter" version of the shocks happening at the tent when I was replacing bulbs. The shocks at the tent were intense enough to cause discomfort. It's hard to tell from the pics but the tent poles are about 10' higher than the lot lights and as you can see, the position of the tent is actually beneath the lines. I was able to draw almost a 1/2" arc from the poles. Every 2nd or 3rd cable that was sewn in to the tent was vibrating intensely. I was surprised they were almost done putting it up. That must have been a long day for the workers as they repeatedly got shocked. They were trying to complete the building process by pushing each of the main tallest poles into a perfect vertical position. That is when the shocks became even more intense and they finally thought they should ask someone about it.
