My wife and I will be travelling to your area late June. One day in Koblenz, 2 days in Bonn, then off to other places. Perhaps something is possible. My wife is only interested in wrestling not catfighting, and is very inexperienced.
She is 44, 5'8" 170lbs.
She has only done something like this once before, and I am not sure how keen she will be for a second event.
If you are interested, I will ask and see.
