If you can't shoot a big buck I still don't think asking you to bring your own equipment is out of line....Stand/Blind ETC.
I personally think half the food plot may be crossing the line but Specifics would be important though. To me your hunting equipment is completely your responsibility so I'm just going to through that out all together.....You definitely don't get any control just because you brought your own deer stand/blind.
I guess it really just depends on how much money he wants you to spend on the plot.
