Craig, welcome to N07! A quick local note, you'll notice the CDW Delta is very close to the south end of the airport. The airport manager at CDW has assured everyone in numerous pilot meetings that you can enter the CDW Delta while departing runway 19R at N07 as long as you don't go any further south than the train line. It doesn't give you a ton of room, but it's enough to turn west or north to get outta there, or enough time to swap to CDW tower and call them for a formal transition.
If you need a ride from the bus stop to N07, I'll shoot you my cell and if I can pick you up, I will (I live about 5 mins from N07). I normally work from home and have a flexible schedule.
If you'd like to meet some local pilots, check out Mid Atlantic Pilots Association on Meetup, they have a meeting coming up on Thursday to review ICAO flight plans. There's also NEPilots on Meetup, they have fly outs pretty regularly.
