Charity Rowing

I have never seen any notices anywhere for "row for charity".
Do you have any examples?
In my part of Texas, nobody rows!
They kayak, canoe, or powerboat, but they don't row.
It's actually very rare, unlike running where a lot of companies sponsor those types of events. I think rowing is a very niche sport, that's why. They may not be able to attract that many people to participate in it.
