PROS no longer conducts tours  our research site is no longer operational.

Email us for private tours, interviews, or investigations.

PROS will not be conducting investigations at our research site (LTRS) every Saturday night.

Our investigations were broadcasted live on our webcam page. We no longer conduct tours at our site after 7 years.

Public Investigation of the PROS LTRS Guthrie Ok.

The LTRS is an old warehouse that dates back to the late 1800s. It has been the final stop for our Train Depot Tour the last couple of years. There has been paranormal activity reported there for many years. The activity reported ranges from strange noises to full body apparitions. PROS has been conducting long term research at this site for many years. We are aware of the activity that happens around our team members that are present week after week. We have noticed at times during our public investigations with new people at the site there has been a change in the activity. We want to start recording this activity and comparing it to our regular investigations.


Join Pros for a live investigation of the Long Term Research Site. Be part of the PROS LTRS 2011 Research Project. We will start the evening with a seminar covering the theories and techniques used in paranormal investigating. The tools and equipment we use will also be on display for you to see and inspect. After the seminar and a Q&A session, the guests will take part in a serious research investigation. 

Again PROS no longer conducts tours at this site.
