Hello. I am in Murrieta, just down the I-15 from you. A good place to get started is at some of the old school, railroad station, or church sites near you that may be sitting empty. Reading a good history of Riverside (as I am doing now) will let you know the location of some of the original parks or water holes. You can look in old newspapers to find out where the circus set up when it came to town, or a local fair. Ask some ofthe old timers who live near you. You are also close to March Air Force Base, which began as March Field in 1914--plenty of people were concentrated in a small area, camped out far beyond the boundaries of today's fenced base. Think of anywhere where there were crowds of people, preferably with money in their hands. Combining research with your detecting will add to the metal detecting experience. Good Luck!
