GC1RBPF - Post Office Box Series #1

The next geocache found that day during my travels was this one, GC1RBPF. This cache was the second part of a puzzle. I've looked for this one several times, and never seemed to be able to come up with it.

I thought that since I was passing the location where the final cache should be hidden, I would try again. I looked around where my GPS was putting me, and again I couldn't find it. But I also know my GPS can be off by as much as 30ft at times. So I started walking between the locations it was taking me too, when I located something that just didn't look quite right to me.

So I walked over to the area where I thought it could be, and got lucky with the find. I will say that when I was looking in the spring/early summer for this one, there may have been too much growth for me to find it.
