Here's the directions to Bushnell Tanks:
You go north, turn right on your 13th stop light, then left on your 5th stop light, count from 0 to 17 and you should see a right turn, but dont' turn there, start counting over again from 0 to 16 this time, then you'll see an other right turn, take that one. then you go, start counting again from 0 but to 893405 this time and you'll see a dirt road on a side, turn it there, then follow the trail and you'll see this one piece of rock on a side, pass that. then you should see a bush, not too big, but not too small, and you should see a tree right next to it too (maybe 2 trees, I forgot, but I'm sure you'll see it) then you take a left there, go straight a lil bit more and you should be there.
