Ethnography: Use of the climbing wall

I want to track use of the climbing wall at the rec center. The idea is to track how often a wall is climbed on, what rope used, the gender(s) of the climber(s), if there is a new route on the wall, and how much time the group spends at a single wall. If it is only me working on this I will only be able to monitor two or three walls adequately. I will plan to do the monitoring 2 hours a day 4 times a week myself, and add time and walls if other people want to do this as well. This will let us know who climbs what types of walls (e.g. - over hanging, slab, vertical) and for how long. I have talked to some of the wall staff and they are willing to help out getting data as well.
