Tom, et al: I just spoke with my darling daughter who now works at Bilenky's (Woohoo! Both for her getting any job at all in this economy and especially for her scoring one in the steel framebuilding field so dear to all our hearts.). Philly Bike Expo is *definitely* happening. I (and she) have no idea why the website is not responding to your inquiry, but if you want to contact Bilenky, write Ray at Bilenkymedia@gmail.com. He promises to respond.
