Chester County - I have an uncle out that way, in Media.
Beekeeping is a great hobby for you and your son to share. Start reading! Check your local library for books & videos. Check out the "How to Start Beekeeping" subforum: there are many great suggestions covering the basics.
Get involved with a local beekeeping club. Clubs often offer classes for beginners and are great places to find mentors and get connected to local beekeepers. Much of beekeeping is "location-specific", and so the local guys can help with what works best in your area. http://www.pastatebeekeepers.org/Reports/Map/Contacts and Inspectors.htm#
