Interesting, Alan. My sister lives in Alpine. I don't think we can get to BB this year, because we are going to Arizona in March, for some of the spring training baseball camp shenanigans. But will be interested in how things go for you at RGV - maybe next year we could plan on it (assuming you love it and have a do over).
FWIW, I think there's a Casita gathering in Lajitas (Casitas in Lajitas) either this month or next. Maybe some of them will also spend a couple nights in RGV.
