i don't want to sound negative but,,,,, If I was you I wouldn't say to much to your son until you get the actual call! My son drew it a few years ago and never got a call to hunt at all. He was so excited with the draw and then when he didn't get the opportunity to hunt it became a big let down. Really frustrating for me the father. I contacted the game dept and asked for them to re-issue his points and they said "no way". Really made me mad. I understand that hunting is hunting, but drawing the tag and not ever being able to hunt at all is a scam if you ask me. If he hunted and wasn't successful it would have been ok. I have just heard a lot of youth get this tag and not be able to hunt. I do also know that a few do get to hunt and they have had some amazing experiences. I hope your son has a better experience than mine. Or I should say, I hope your son has an experience at all!!
Also, Be ready for them to call you on an afternoon or evening and want you there in the morning. If you live out of the area, to bad! It might be on a weekend or weekday. I sure hope you don't live on the west side, if so you will have to drive all night to be there on time. If they call you once, they feel they have met their responsibility and they will NOT call you again. Remember, they give these tags out so they can get bull tags from the state to sell to big money paying clients. Silver Dollar ranch also is a group of ranches and you will be assigned a certain ranch (we were assigned the Martinez ranch). That ranch and only that ranch will be the one who contacts you to hunt. Some of the ranches go out of the way to get the kids hunting. Other ranches love it when they call at the most out of the ordinary times and you cant make it. I know four or five people that have drawn this tag in the past. All but one got to actually hunt. My son never got a call at all.
