Hey OBG,
You can hang out with me if needed. I have been told more than once that I am the south end of a north bound horse. You'll quickly learn which way north and south are from that stand point.
I do this pretty much in the night time since I do a lot of amateur astronomy. I the daylight hours, (when not sleeping) I usually am familiar enough with the area I am visiting to know which way north is. Though a compass and GPS do come in handy from time to time.
Still, it's a very useful tip.
