Visited some benchmarks with Frivlas today.

I admit it, I have driven by this tons of times and never knew this was here. Popped over today and made the quick find of this interesting benchmark.

I tried to go by slowly, but the guy behind me was in such a hurry. Came by a second time to show my daughter.

Drive by find this morning while over here to grab a new puzzle cache.

Easy find, I've driven past here probably 100 times, looked up the benchmark. I didnt even know it was there. Coords were off by nearly 500 feet...

Easy to find from the Survey description.

Found it in good condition. 50sumtin

2nd benchmark today.

-The Buggy Bunch

This benchmark is near Sally's new workplace. I found it while she was touring the new facility.

Found it on the third drive-by attempt. The other days I tried I looked in the wrong place (to the left) as I slowly drove past. Got it this time though, it's still there.

At first I was looking at the wrong part of the interchange, but just as I was leaving the area, I realized where this must be. It was an easy find after that.

Must be very alert when going for this one.

One of the newest benchmarks I've seen. It was difficult to figure out where to park for easy access to this side of the road. Benchmark is in good condition.
