I visited the Old Wilson County Jail Museum to perform a paranormal investigation. The museum operates during the day at a very affordable $2 per visitor. I performed a paranormal investigation on a Saturday night from 8PM - 2AM thanks to the very accommodating owners. They've hosted a few paranormal groups in the last year, so they are very much paranormal friendly. If you have ever been curious about being a ghost hunter, this is a great place to start. We caught multiple Class A EVP's and the prison is easy to navigate. If that's not your thing, visit during the day. Can't beat the price and it's proximity to San Antonio, TX.
