Collected one small juniper from aunts house outside flagstaff. And got a couple oak seedlings she had. But you should see the photos of the ones I couldn't dig up.
Didn't have much luck near sedona as everything was owned by one forest or another. But do know a guy on the backside of big bear if your ever near that would let collect for a fee. Which I've done a lot.
leaving earlier than planned might not get to now. gonna get there for thanksgiving. but at least now i get to se zion and bryce as well as sedona and petrified forest. collectected a ash tree recently you'll have to see.
