I have hunted at 37B for many years. I have always seen javalinas up elgen wash to get to it you have cross dudleyville turn right like your going back towards hayden go approx. quarter to half a mile I think its the second wash under the old railroad tracks and follow it up you will come to waterfall that you to walk up over with your vehicle you can see where everybody does it and follow it will climbs out to the top of the hill you look southwest you will see antelope peak if you look north you will see hayden if look east you will see san manuel and mammoth area from the river to the of the top hill on both sides of wash I have seen pigs all the time or you can follow the river road to the campground wash go up it to the water running theres a big canyon on the west side theres roads up there that you can take and you will see a lot pigs. I have done a lot of coyote calling in the area and got some pigs there before. Good Luck! P.S . camp grant is the old name but its across the aravapia canyon and if you get on google earth you can find it.
