South Dakota birding coming up

I'll be heading up there for a few days (11/3-5) to move my husband to his new job in Rapid City. We'll have a commuting marriage for an unknown amount of time after that. In SD on my visits this winter I'm hoping to see more Snowy Owls and Snow Buntings than ever come to Texas, and maybe a few birds that never or very rarely do (e.g. Gray Partridge). But most of the time I'll be in Texas, working for my patent clients, doing a few local birding trips I hope, and fulfilling most of the various volunteer commitments that I promised to do.
