I meant to reply when this thread was fresh a month ago but got busy hunting. Anyhow...

I had some good success this past year on mule deer does with a Crit R Call peewee. My son had a doe tag and I was able to get him several good shots with simple fawn bleat distress calls. He wasn't able to connect, I think due to nerves, but the calling was definitely an aid. Does didn't always come in, but sometimes it was effective to get a doe moving that was bedded down that we couldn't see at all. Once up we would try to figure out an approach, even if it didn't come closer. There were a couple cases where the does came right to us out into clearings.
