Like most of these other guys said, the key is respect. I am a 19 year old kid. So it would be harder for me to get on hunting land, but I do. tell him/her exactly what you are going out to shoot. dont leave any trash, and if its a farm always ask to help with the farm ex. cattle, chickens, etc. and most likely if the owner does not hunt and has a farm he/she will not mind. they eat a lot of the crops. if there isnt a farm then just ask to help out. perhaps mow the yard. and always ask if they would want any of the meat. and if worst comes and you really have to hunt that property, you could always ask him/her to rent for hunting. like 50 for a month or something along that line
