Saw it while looking for another mark in the area. I forgot to take a closer picture, but I got in in the background of a more distant photo.

My favorite [red]bird[/red] and I flew south for the day and had a blast engaging in all of our favorite things - benchmarks being one of them! We drove right past this one on our way from a benchmark in Homewood to a two-fer benchmark spot in Frankfort. This was benchmark #5 of 7 for the day.

Ike had the perfect day planned for us over a week ago but I got sick. Today we got to see this plan come to life after the Belly Lauging Day event with a couple good caches, 7 benchmarks, 30+ trackables, the standard shenanigans, steak and shniz 5 ways, and a trip down memory lane. Isn't she the best, oh and [b][red]TanksFTBM

Spotted this from the nearby Texas Roadhouse eating spot. We have been by here for 30 years back when LaGrange road was a 2-lane country route to Kankakee.

I had to settle with spotting it from .5 miles away, but I took a picture on this grim and gray day anyways. Later in the day while on the way to Lockport I drove past the tower once again.

Not the best day to take a pic of this tower from a distance, but it's still there. Pic was taken from the frontage road in the area of the SXU caches.

This has been a local landmark for a long time. Lots of teenage parties, out by the WLS tower, before the area got so developed.
