I am new to this board and have only been caching since June BUT, I have already learned that I had rather do a difficult cache than pull up to my local Wal-Mart and sit next to a lamp post and sign the cache log without even getting out of my car. There was not many caches in my area and what was here was not very difficult and since I have been caching I have placed some very ingenious caches out and although there seems to be alot of DNF's people in my surrounding area really seem to enojy the hunts becuase they can't wait to see what is coming next. I recently did a cache that was an Ammo can and it was in a 12' high pile of stumps abound 75 yards long and you thought you were hunting a nano which in fact you were but it was in the inside of the lid of the ammo can. There was also alot of red decoys stuck in the pile to throw you off. This cache was absolutely fun. I have placed a dead bolt on a metal door, sewn leaves in a bush, a nano rolled in crushed churt in a churt pit with an ammo box decoy that when opened stated now you know I can hide an ammo can let's find the real cache, I also like creating a unique puzzle cache. There is a couple in my area that will not even hunt a cache if it is rated less than a 3 on the difficulty. So I think that is a great cache idea, I would laugh my rear end off when I opened it and saw all those nuts and bolts and so would most people in my area. Anyway I will get off my soapbox now, I would say rate the difficulty high so that those who like lamp posts will not bother with it anyway.
