Fly fishing has always been a presidential sport, at least in the good old days. Presidents took more time off, sometimes up to three months, so the opportunity was there for them to enjoy some quiet days on the river where the biggest problem they encountered was deciding between a size 14 or 16 dry fly.
Fishing seems to be one of the few avenues left to Presidents through which they may escape to their own thoughts, may live in their own imaginings, find relief from the pneumatic hammer of constant personal contacts, and refreshment of mind in rippling waters. Moreover, it is a constant reminder of the democracy of life, of humility and of human frailty. It is desirable that the President of the United States should be periodically reminded of this fundamental fact — that the forces of nature discriminate for no man. – Herbert Hoover
