ya man, thats the place. and if you go some time, il come along with my savvy for some bashing. the pics make it look really flat, but its a pretty deep pit. its like 10ft deep maybe.
...now, i forgot to mention that it is like 3/4 of a football field away from the closest houses, but the great thing is that im pretty sure nobody cares because there is a railroad literally right beside the pit. so when a train goes by its loud as a motha and you cannot hear even a big block.
Also, some bikers keep it clean, and add new ramps once in a while so its not totally rough.
edit: thanks for the map
