The catch of the month were obviously the 3 RCAF CH-146 Griffons that rotated through P72 on a ferry flight to training. They took off in a formation after spending three days awaiting weather in Philadelphia, and provided me with some great photo opportunities. The EC145 in Air Methods house colors takes the close second, as it has been a while since I've seen a helo sporting the Air Methods house colors. The last one of them was probably also a Jefferson spare.
