I would like to echo that. I've been on the front lines on these harbours as well. When you're walking the floats and trying to answer questions about why this isn't fixed and why it is like this.... Those people on the front lines get a lot of abuse. I got it first-hand myself, and sometimes you don't have the answers for them. There's the stress of that to add to the fatigue.
Also in life, and I think in every community, you see the same people who volunteer all the time. It's always those people who step up to the plate. They're starting to age, and it's hard trying to find new directors who will fill in. All of those aspects, the exposure and the safety that these people deal with as volunteers, are huge. It's asking a lot of people, but there's a lot of good people in the program.
