When I visited the Ghost Town, Melmont, I placed a Terracache near the old school remains. Later when I made my post, someone pointed out that there were three Geocaches enroute to my TC. The last GC was within 15 feet of my cache. But the exact location of my TC and the GC were in such a way that you would have to be way off to stumble over mine.
Funny thing is, that I was MDing near the GC hiding place, and once you find a few GC's, they get easier to find cause of the tell tail signs.
A tip for finding GC's, for the matter TC's also. Look for a trail. A trail will sometimes lead you right to where your going. People of habit, all they can think about is finding it and leaving.
Another tip, is the 2 stick rule. If you find 2 sticks paralleled to each other or more, chances are there may be a hidden prize beneath it. Nature doesn't drop sticks down so they lay flat side by side. But a path to a locatioin that has 2 sticks near a crevice or corner...hmmmm.
Anything hollow is a potential hiding spot. I have a TC hidden in an old construction concrete pipe. It had been there for years, covered in moss and ivy. I block one end of it with some big rocks, but put them in the tube, so if you were to look inside the wrong end you would see nothing. The right end, well, you will just have to do the puzzle first to find out whats there.
Most people, well about 99% walk looking down at the ground. Anything hidden just above the shoulders will be invisible to you. Such as someone pointed out with the polka dotted bra just above there head. I also have one planted in a tree, but I give clues as to the longer you wait, the further the cache will be from you, or something like that.
A cache sometimes is found by non GCrs or TCrs, or called Muggled. Mugglers stumble across a cache, not know what they find. Read the log book, look at the stuff, sometimes they sign the book and take something. But the biggest problem is, they don't know how to rehide it properly. Making it easier to be found again. Even GCrs have that problem too. So if your searching for the box, look for a trail, sticks or in just plain site. Your GC experience will go much faster, which means yuo can find more in one day. My record finds for one day is 15! I know some GCrs that make 15 look like grade school work.
I geocache and agree that users always seem to leave a trail, broken branches, knocked down weeds, it becomes easy to find them once you know what to look for. Mding is funner because you don't know if you'll find something worth something or trash, with geocaching, its just little trinkets.
I rarley would leave anything small when I place a cache. I stocked my caches with gloves, tools, money, tokens, travelers, and house hold useful items. Nothing more discouraging then to GC all day for just one cache and find it full of McDonald toys or tiny trinkets. Its the hunt, not the reward at the end, that makes GC fun. As with MDing, hunting is part of the game, the prize at the end for us is our reward.
Have fun, and remember to take your MD with you. GC and TC will take you to places you may never find without the gps.
Happy Hunting,
Gander
