try looking for a new place to hunt, as them 8 acres,. you might be scaring deer off the land with too much pressure
or start really paying attention to wind and how your getting in and out of the woods so they do NOT know your there
scent can last as well as travel into deer bedded and scare them without you ever seeing them!
start trying some trail camera's, most kids enjoy seeing them, setting them up, seeing pictures of what is there
and again, maybe time to find some more places to hunt, , new lands can add new hope and interest, as well as make for more memories!
have to also instill in kids, that hunting isn;t all about a KILL< its also about enjoying being outdoors, accepting the challenges of TRYING to get near wild animals that have better skills and senses than we do!
only a small percentage of hunters actually KILL a deer every yr!
magazines and hunting shows, seldom point this out!
those are some suggestions from m,e for now
