Riverside/San Bernardino dirt jumps

I recently moved to Moreno Valley and trying to find some good trails to ride. I know of the big jumps off the 60 in Riverside, there is a small set on the north end of Moreno Valley, but I don’t know of anywhere else. I’m pretty new to jumping bikes, used to ride a lot of motocross and been mountain biking for a while. I’ve checked out the jumps off the 60 and they’re sweet, but quite a bit bigger than I can ride at the moment. There aren’t really any smaller jumps to progress on there. Are there any trails in the LA area that have anything good for starting out, maybe tables or just small gaps? I’d of course prefer something closer to my area, but I don’t mind driving if I have to.
