Right, because it is sooo hard to lift up the base of a lamp-post. Micros are typically much easier than regulars, even if it is only because of where they are typically placed. I will agree that a micro in the same location as a regular will be harder, but most micros are much easier to get to than most small/regulars.
For me, geocaching is primarily about the places you go, and after that it's about the things you find. I go to parking lots all the time, I don't need a cache to take me there, which is why I'm not a fan of most micros.
