I got up early on Saturday morning and beat the gusty winds that were moving through the area. It was smooth at 3000' but got pretty bumpy down low. Gusts were up to 16kts by the time I got back to Quakertown. It was still gusting on Sunday, enough for me to cancel all flights for the day. I suspect it won't be too long before the winds are driving snow.
PPL Center is a sports arena in Allentown, Pennsylvania that opened on September 10, 2014. Its naming rights are owned by the PPL Corporation, which is headquartered in Allentown. PPL paid an undisclosed sum over ten years. The arena is part of a larger redevelopment project of the central business district of Allentown. The project encompasses a 5-acre square square block area, in which several new structures are planned to be erected. Part of the arena site was previously developed in the 1990s as an office building called Corporate Plaza; shortly after opening, on February 23, 1994, it collapsed into a sinkhole, due to limestone in the ground and the decision not place the building on a concrete pad, but rather on spread footings; the plaza was imploded on March 19 of that year.
