Gwynedd-Mercy has wheels. And those wheels were rolling at the Lower Moreland Invitational as their 4x400 squad set a meet record of 4:06.7; Khaki Mealey went 2:21.3 for another ; and distance runners Kate Vernon (1:01.9) and Kelly McGrath (1:02.2) got in a little speed work entering the last few weeks of the season. Holy Ghost Prep's Kevin Corson won both hurdles events, going 17.8 and 44.1.
