220 has hot spots in a few places.  Atlanta has a couple (one actively used) and I have heard APRS on another 220 frequency.  I spotted it one day when I scanned through 220 on my D700.  When I heard it, I let the radio decode it and sure enough it was APRS on 222.090.  As I understand, California is also a hot spot for 220 activity.
