A while back, my husband and I went on a cleanup of my section of I-5 in Grapevine Canyon. While cleaning at the upper watering hole on the southbound side, I noticed a bit of newspaper. When I grabbed it, the first thing I noticed is that it looked rather old. Normally, when I find a newspaper out in the field, assuming it is not too dirty, I try to find a date on it. I’m always curious how long it may have been out there. This time, however, I saw an advertisement on it that told me it was older than normal. The ad was for Six Flags Magic Mountain and was for a ride that had been gone since 1986. Looking a little more at the paper, I found a date, Sunday, July 1, 1984. As the cleanup was in late July 2018, I was rather amazed at the find.
The ride in question was known as the Sarajevo Bobsled, a ride named after the location of the winter olympics in 1984 and was an Intamin bobsled type ride. The ride was closed in 1986 and moved to Six Flags Over Texas, where it continues to operate today.
The portion of the paper I saw first.

Another time I found a Los Angeles Herald newspaper from the late 1950’s hanging onto a railroad switch near Holtville, CA in the Imperial Valley. You just never know what you might find out there.
I went on the sarajevo bobsled at Magic Mtn in the summer of 1985, felt like your typical roller coaster ride. It was fun.
great find!
