I've gotta agree there. 121.5 is for when you're not talking to
someone and don't immediately know who is the best contact. At times
when I'm not getting flight following, I stay tuned to the appropriate
Center or Approach frequency for the area in which I'm flying. Even if
I happen too be to low for ATC to hear me (quite common in the
mountains), I know that there are airliners overhead that will hear me.
If I need help, it's just a button push away.
