Thanks Ozmo.....
The problem with landmark are sometimes they are closer then they appear. I can see fine (with glasses) out of one eye. Just the depth perception thing. About a month ago I had a tree reach out and grab one of my planes and I thought I was a good 30 yds from it.
I clipped a drag(farm implement) in the pasture I fly outta landing another, it was a dead stick though so I didn't have much choice.
I aint gonna let it stop me. I give up the booze to get back into planes, been putting off RC for 30 years.

thanks again
