We have a ton of javelina here and they aren't shy. The coyote tend to be shy, as are the bobcats who enjoy the pack rats and rabbits.
When I take my dog out at night, I bring a flashlight and shine it into the brush and have seen javelina eyes pretty close, watching us. One night, a few ran across the driveway in front of us, but a good sized male broke away and came at us. I bring a LCR with .22 high vel rounds in it, drew it and took one shot. He immediately turned and ran into the brush. Next day I found him DRT about 50 feet into the brush, seemed over 50 pounds. I couldn't find the entry point, but it must have been a good one.
I hate those things, I've actually heard them on the front porch.
