I've heard some complaints (not from here) that micros in parking lots, guardrails, lamposts, etc., are not in the true spirit of geocaching and that since there's no real challenge then they're pretty much pointless. Being so new I wasn't sure which side to take for a while. Until today.
I found a new way to look at roadside micros. I went out today to find one of the 101 Dalmations. It's just a few miles from my home and decided that rather than do it as a PNG that I would run to it! I ended up running about 5.5 miles today to do a park and grab! It does in fact make it just a little more rewarding. I'm preparing for my first 5K and decided to tackle this as part of my training. Since I started caching I've lost 28 lbs by walking to caches, many of which I could have just driven up to. So I guess I don't really have a problem with these PNGs, it's really all how you look at it. Just thought I would share.
