The fog came back today
September's secret to good fishing
a flurry of fish rush to the river
as it rises on the tide

I walked the river long ago
when the children were young
finding a fish on a dragons tooth
swung long and low
losing the big fish
to lady Caroline

Today it's different
I leave the rivers be
and search in the salt
with red eyed minnows....

I met brother heron on that river though
and he follows me everywhere I go
