Same here, BP.
I enjoyed my customary spot & stalk in a field where I do this every year in the late season it seems; they know I'm there but play along. Ended in a mexican stand-off w/ a young doe staring back at me while I looked down the sights at her. Finally just before sunset, I stood up & waved her and her pals off-for next year...
Took the long way out and stopped by a few spots much as you describe just to say thanks and bid adieu. These places have taught me a lot about both hunting and myself over the years, it's good to appreciate them.
I reached the van just as the stars were making their appearance, turned the key and 2011 was in the books. Already I was thinking what I will do differently next year.
