...After Circle T closed the tracks and fixtures were sold and moved to Santa Paula CA where the new owner operated a raceway for 3-4 years.
I don't know when Circle T closed but when I got back into slots in late '88, I went to Racemasters (Russ Miller) in Santa Paulicide (as Russ fondly calls it). He was in biz till about a year after we opened FlashTrax in Oxnard ('93).
Russ still has the tracks in storage and keeps ranting that he will open again

Also - Don - Thank you for posting the article on Playland. While doing my mobile track thang around the SF Bay Area in late 90's, I randomly heard folks talk about it. Then several years ago while visiting my sis, who lives 40 miles into the Sierras from Sacto, I ran across a fella who had bought all the tracks when they closed. He said they opened but it was such a huge project and the book had busted, they didn't last long and went the way most do...forgotten and abandoned...
