For some odd reason google maps doesn't show you the lat/lon as your browsing around the map.  Occasionally I've wanted to have that information since often times I'm trying to reference a point way out in the woods for a backpacking trip or whanot.  A quick and handy way to get that information is:

1. Google map your way to the spot in question.  Make sure the map is centered on the exact spot your after, (such as a trialhead or destination :)
2. paste the following into the address bar of your browser.

• javascript:void(prompt('',gApplication.getMap().getCenter()));
