For me, the pool has the advantage of being a simple and quick after-work possibility. No gear needed, 2 mins from the office. I don't see it as a replacement for real (as in outdoor) paddling, but as a supplement. I am not a gym guy. Did it for a few years, but always hated it.
Anyway, I understand that it'll be hardly possible anyway.. What about dodder in the early evening, I assume we can use club playboats? But we always need committee around, right?
