im thinking of making a 10 by 10 patch of whiteail food plot in front of my stand but many people hunt this land so u think it would be worth it and would it last or would it be eatin in like 20 min

its hard to say, if you put good stuff in there like strawberries, the other people hunting might eat it.

10 by 10 is a bit small, and it would depend upon what else is in the nearby vicinity.

What you're talking about however is a "harvest plot".

First ensure that doing so is legal in your state and check out this article:

If it is like Pa. Everyjerk will set up on the plot and take advantage of your work
