the buck sign you are seeing is pre rut activity. deer "learn" the openings are dangerous and shortly after the season opens will avoid the fields until after dark. If you have does in the field during shooting times stick with it. the bucks will find these does. in fact they should be well into the chase and even into the rut. the scrapes will show little sign of bucks during the rut cause they are tending does. hunting isn't easy it takes work. work before the season and work during the season and after the season. like most things. Its the little red wagon syndrome. Its your little red wagon. you can push it, you can pull it, you can let it sit there and rust, and you'll only get out of it what you put into it. take this time, and any time spent afield, learning the woods, the winds, the foods, where the cover is, where the most likely bedding is, where the danger is, and deer behavior and habits. this is a great opportunity for you and your son both to learn and discover together. There is tons and tons of info written here in these pages take the time to read them and see what applies to you and your area. good luck.
