Note to the 'small' Lancairs who park in the 'old' 

Lancair parking area at Oshkosh.  I taxied in Thursday prior to EAA ground folks providing guidance causing rudder bottom damage by not crossing a 'hidden' ditch (obscured by grass) via a 45deg method   . 

  Please do NOT cross any dark green stripe of grass at 90 deg.  

I was asked to inform y'all as a reminder by the EAA ground crew this morning.  

If in doubt, shut down until a ground crew can guide you to usable areas and prevent damage.

Thanks, Earl
