With the revival this year of the Catalina Island GP, the first time it has run since 1958, I dug into The Kneeslider research library and came up with a few photos of the early years. I found a couple of articles from 1952 and 1958. Times have changed but some who remember the original races are pretty excited.
From what I hear, accommodations are already in short supply so if you are planning to go, you might want to make arrangements soon.
