It would be nice if Fish and Game would let you harvest your does at the beginning of the season,
I think this would be a great suggestion and you should submit it to your states dnr. The earn a buck makes complete sence if you think about it. You may not like it but it forces you to do your part to thin the herd. If it wern't for earn a buck most people would be content with just shooting a buck and there would be no herd management.
I hear you point though. I could see if you had to tag a doe to "earn your buck" for the early season and a second to "earn your buck" for the extended season but I agree you should be able to get them both out of the way early in the year. If I were you and wanted to get the laws changed I'd email the director of the DNR. There are no guarentees that they'll act on the suggestion but it certainly can't hurt.
