1. April, May, or June works for me. Late June through early Sept is on the warm side. April is usually bluebonnet time, I think.
2. I'm retired, so whatever days are best for those who have schedules will work for me. Make it easy on yourself. I imagine that there would be considerably less traffic on weekdays.
3. I've stayed at the Leakey Inn. I liked it. Very relaxed. I'd also be game for something on a river, too. I'm easy to please.
Time flies like an arrow.
Fruit flies like a banana.
