last checked in with my quest to get all 60 minutes of longitude in 76 degrees West, I had 23. Now I'm up to 28!
One way I've been finding caches to fill in holes is by creating a map that shows where I've already found caches. The vertical stripes are pretty clear; the shaded in areas show minutes I've already covered. (It extends west to 77 degrees.) The top and bottom of the rectangles represent the extent to which I've filled in the 38 North and 39 North latitude challenges in this area. I could create more boxes to show areas I've cleared in Baltimore, but that would be too much work.
Anyway, the bottom line is that anywhere in the shaded boxes will not help me with a longitude or latitude challenge. There are only five strips to fill in between Washington and Annapolis, so it will be challenging to get beyond 33.
The five minutes I've filled in are 28, 29, 30, 32, 39. The kids were in camp in Severna Park this week, which allowed quick stops for 28 and 30 (and a failure for 34). Minute 29 was found in April on a visit to a friend in Essex, Minute 32 was in a shopping center while waiting for the Annapolis MVA to open, and Minute 39 was in the woods near Crofton while passing through.
