Mary designed a little training for me on the West Campus sprint map. I got a stack of cards with little bits of map on them. The map bits were about a square centimeter. I looked at a map and then ran around until I found the location (which was sort of randomly exploring until I recognized what I was looking for). When I found a location, I'd pick up the next card and find that location. Here's a snapshot of the map cards:

It turns out I wasn't doing the exercise the way Mary intended, but it was kind of an interesting exercise anyway.
