Cool website Chicago Cop! I browsed through some of the other photos from that episode:
1. Your image of the Faith Lutheran Church/Timberline Lions Club: That building was not torn down. It's still here and is a community center available for rental. It houses gatherings, events, plays, boutiques, and even the Farmers Market during winter.
2. The bell and those mountains do not look familiar. I'm thinking this was fictional.
3. Oster Realty is no longer in business. That building has been remodeled and is now the Cabin Creek Inn, a nice motel.
4. Your image of Purma Sheriff near the old gas station: That gas station is also no longer there. We have a little gas station and mini-mart across the street from that.
5. The Purma Sheriff Office building is still there. It houses a travel agency/motorcycle tour company.
6. And yes! Wrightwood is a great little town - hope you make it someday.
