by Don Scallen, Vice-President

Before Dutch elm disease ravaged the land this beauty was common. The few remaining mature elms are rare treasures. The lure of this elm was so powerful that I would include Creditview Road on my route to work simply to … Continue Reading ››

Bobolinks and Forks of the Credit Provincial Park
