Visiting the former St Louis factory?

[ThreeQuarter]

Has anyone visited the site of the old St Louis Truck Assembly that built our pickups (including mine)? The facility is now a business park called Union Seventy Center that leases space to other businesses for manufacturing, warehousing, etc.

I am hoping to take road trip in my '68 this fall that would take me through St Louis, and I'm wondering if it's worth the time & effort to stop. As you would expect from a 100-year-old industrial site, it's not in the best part of town anymore. I think it would only be worth stopping if they had a display that paid homage to its former purpose, or at least a good photo op where I could park in front of some GM logos.
