Every warning is given for a reason and this doesn't just apply in Utah, it applies everywhere: don't set up a hammock in an electrical tower!
The Weber County Sheriff's Office shared a photo on Facebook of how some adventurous people climbed an electrical tower to hang a hammock. Sure, the view is great, but the potential of getting hit with 75,000 kilovolts of power isn't really worth it.
Don't put your hammock on an electrical tower, ding dong.
