Richard, you are clearly intelligent and do make some reasonable points, and I do find myself agreeing quite often with what you say....if not usually the way you say it
However, in my opinion, and dare I say it, that of many others, "clearing a swim" should involve the least possible disturbance to the bank side vegetation and wildlife, such disturbance being no more than that required to gain access. If the above is your idea of "clearing a swim".....then might I suggest that golf would give you more of the open spaces you seem to prefer
OK, the tongue WAS firmly fixed in cheek Richard, but it's Christmas...and I couldn't resist it
Cheers, Dave.
