    Ron Haimbaugh by Ron Haimbaugh

    Most of February had been quite cold and I was concerned the creek would be totally frozen. Fortunately the last couple of days had temps above freezing. There was a gap in the ice just large enough for me to drop the sampling pail into. Since I took the sample last week, we have had warmer weather, but who knew.
