If the deer want in,there going in.One guy here put a deer fence up and an electric fence on the other side to keep them out of the fields.Now they walk in on his driveway.I would put in a chainlink to keep people out,then leave gaps where the deer can come and go for water,but put it in a place where a guy would have a hard time finding it.Im still thinking about the pros-cons for a while before i do it
