Driving around the country, there are many places where you can hear stations from two or more markets. This enables most of the frequencies to be filled with stations. There are some places you can hear stations from three or four markets.
FM- Anywhere from Walterboro to Santee, SC on I-95 (about 50 miles). You can readily hear most of Charleston's FMs, plus the strong FMs from the Savannah area (98.7, 106.9, 97.3, 102.1, a few others) and the strong FMs from Columbia (97.5, 106.7, 107.5, 104.7). A couple of stations from Augusta, GA (104.3 and 105.7) can also be heard. That's four markets.
AM (not counting coastal areas, where you can hear multiple markets readily within 10 miles)- Maryland between Baltimore and DC. Can hear any DC or Baltimore station, plus York, PA (WSBA 910), Harrisburg (WHP 580), and a couple of other markets.
TV- Daytona Beach, FL. Back in the analog era when I could hear TV audio, during one summer night there I had every channel from 2 to 13 with a different station. 2 from Daytona, 3 from Tampa, 4 from Jacksonville, 5 from West Palm Beach or Charleston, 6 from Orlando, 7 from Jacksonville, 8 from Tampa, 9 from Orlando, 10 from Miami, 11 from Savannah, 12 from Jacksonville, and 13 from Tampa.
