I assume you mean this? Neil Armstrong's bootprint.

It was Wetherby Shambles (GC2H9A2 - login required).

There's quite an interesting discussion thread on the topic at the Geocaching Forums as well.

Or your could keep all of the road information available in a large database, something similar to google maps, perhaps.

And that seems to be what they are doing, which is inferior to being able to read local signage for reasons such as the following:

Opps

GPS can determine heading in two ways.

Actually a GPSr could also determine heading a third way, from Doppler shift. That is how speed is calculated (and doesn't require an accurate fix).

However I know from experience both a Garmin eTrex and 60cs (with the sensors turned off) do it from positional changes.

The problem with your second suggestion of lining up two receivers is this quote, "A man with a a GPSr knows where he is, a man with two GPSrs is lost." Put the same make/model/software units side by side and they will read amazingly different locations. Here's a plot of dozens of GPSr readings of a National Geological Survey benchmark--and that was at a beach with clear skies and fabulous accuracy!

Looks like Rudolph's misfit train will finally have a purpose.

Have I got news for you.

I've been Geocaching for just over a year. I started out with a Garmin eTrex Legend (cheap $125, durable and simple) and just recently upgraded to a Garmin GPS Map 60CS. I absolutely love this thing!! For suggestions on what to buy to fit your needs and what to avoid I would suggest looking at the Groundspeak forums. http://forums.groundspeak.com/ Hope this helps.

I wonder if this was the same outage that took down Geocaching.com? Talk about your worst case scenarios...

And get something like this?

check out this thread (login required?) from 2 years ago where a cacher got a ticket for "treasure seeking on federal land" when a ranger discovered a hidden cache.
