Sorry to hear about the otters...It sounds like your job has big highs and big lows too. But you are doing such a worthwhile job--it's awesome!!!
I think you're attitude is good for the visit. Just a good attitude. No expectations. When I first came to this site, that was a big saying around here. And I think it's good. That way if it doesn't work out you are kind of prepared, and if it does work out, you're pleasantly surprised...
