Multitech training (30-11-2011)

This is the 2nd time I do this exercise. The first part of the corridor went much better this time. But then a huge classic mistake (parallel error). After crossing the road we passed the first sinkhole (yellow circular 'hole'), we were actually running 10m north of the corridor, embarrassing...
Last part: found control 13 this time but the map is really strange 12-13.
Most of this terrain is very nice, especially the rocky area with stone pillars. The map is so-so
