Interstates I've Driven and Ridden

I have lived most of my adult life in the South. Hence, most of my Interstate driving has been in the South, as this map shows, the West Coast driving being mostly my moves back and forth and back from California. The yellow are the Interstates, the purple those I've driven.

However, if we include driving from when I was a kid, and my parents took me with them on various trips, my West Coast Interstate experience increases exponentially. Most of the Interstates I knew, in fact, back then were western. The few Northeast Interstates I've ridden on are from trips I've taken as an adult, which generally involve flying to an area to visit with others who then drove me to other places. The yellow are the Interstates, the purple are those I've driven, the red those I've ridden.
