If I were you I wouldn't freak out. Number one I hunt many of times 70 yrds apart. It's required because you never know what direction deer will take at the crossroads. Two, use this to your advantage. see about getting access on the next property. Explain that there may be days both of you want to hunt there and to give them room rather then competeing for the same deer you would prefer to look for another spot to hunt but your limited and would like to cross over. Three I doubt you two would meet very often. If you do your hunting one spot too much.

Good luck
