You are looking for a large/x-large camouflaged plastic container with tons of trinkets. Watch for muggles! Cache on!
"Ya Be searching for me treasure chest", said Mr. Krabs. " If Ye find it be sure to log it, and give up some of ye bounty in trade for mine." You are looking for an ammo can, well hidden. The terrain used to be a 1.5 however it seems that the wooded area is growing a bit without park maintenance clearing it out the terrain rating is going up. You are a big kid and can handle this. Much love to those who search.
