I remember reading somewhere a couple years back that one of first couple of
707's is still flying somewhere in the US, I think in Florida. I haven't
been able to Google any info, so does anybody know the plane I'm taking
about and if so is it still flying?

Are you thinking of N70700, Boeing's first 707 prototype (367-80,
aka Dash 80)? It's kept in Seattle and Boeing still flies it out for
airshows and such.
