RE: just wondering..
You stated you don't need the meat or anything...you just love it. So why not wait and see. If you see 20 does in a given season then whats the rush? Why do you and dad sit right together? Is it age, safety or just the way dad likes it?
It sounds as though you have your mind made up, you'll shoot your doe and then hunt your buck...that is fine. However you never know whats tailing that doe you decide to shoot...so in some cases it is worth the wait but guess what no gaurantees!
Have fun and do what ever will make you happy. Sounds like you would like to branch out on your own a bit. Have you mentioned this to dad? If not and it is legal than do so. Tell him he has taught you well and now it is time to try and test the knowledge on your own. Again only if it is legal to do so.
Good luck and be safe!
