It would appear a bunch of old antenna towers are being put up for sale. Some are on owned land, others on leased land, but there are several in the list over 300ft, and one which is 580' in Texas.

No idea what they'll go for, but it is surplus...

ps. I'll miss you, Rob. I wish we'd had the opportunity to hang out more.
