I was riding back on the path along the side of the Trent in Newark, and MY GOD the amount of midges and assorted tiny flies by the river and under trees. Seriously a case of head down as much as possible, and breathe through the nose! I guess it's that time of year.
They have noticeably gotten worse in the last week. I have struck more flies in the last week, than in the previous 3 months.
