I have noticed this too. My "micro" finds percentage is going up and up, only because that is what most of 'em are now. There are some good reasons for them (urban, muggl-y areas, and --as in one of my hides-- a desire to make it a special challenge to find. But, I also have some larger containers out there too, because I like the ones with "lotsa stuff in 'em" as much as the next cacher! In the woods especially, there is usually room for something that will hold some stuf. The biggest problem, though, is that its getting harder to move TB's along now! I really enjoy that part of the game, and it has gotten frustrating when I have a large TB that I just can't find a home for, for weeks at a time:)
