Hello Delta Green,
It's nice to see a "somewhat" local contest holder (Sacramento area here). I was not sure if you prefer a single prop small plane or more of a Learjet / Citation or Caravan. I wanted to give the logo both a classic but contemporary look.
Also, I have tons of personal Yosemite photos to reference, so if you rather see the whole valley represented, I can do that too. Your thoughts, feedback or revisions are always welcome. :)
Thanks!
Marcelo
