Loma Linda Fields
Baseball Field Park is off Van Leuven and enter into Entrada del Parque. If you type "Baseball Field Park in Loma Linda, CA" in google maps it will pop up, but so far it doesn't on other map sites. However, if you enter "25548 Portola Loop, Loma Linda, CA 92354" (the closest appartment complex), it pops up in all map sites, and you will essentially be at the fields if you follow that address with your GPS apps.
Leonard Bailey Park is next to the Bryn Mawr elementary school in Loma Linda, on the corner of Whittier and Lawton Avenues in Loma Linda. If you follow the address to the school, 11680 Whittier Ave, Loma Linda, CA, and park in the lower parking lot, you will be in the right place.
