I liked this two stage puzzle - especially the flag part where you have to use logic.
We got up early today with the aim of getting 40 puzzles today for the Forty Sortie challenge. We left home at 6:30 and arrived at the parking co-ordinates at 8:00.
This was our first find of the day. It took us a couple of minutes to locate it - a little worrying so hopefully we'll get some quick ones soon.
