There will be a special reception, program, and book sale and signing for the book Viva Texas Rivers! on Sunday May 8 at 3:00 PM in San Marcos. The lineup of participants is truly impressive. If you plan to attend, you can RSVP to the Wittliff Collections website (see below).
The Wittliff Collections exhibition space, located on the campus of Texas State University, is open from noon until 4:30 on Sundays, and this would be a great opportunity to visit the exhibit of Viva Texas Rivers! that is open there through May 31. https://www.thewittliffcollections.txstate.edu/exhibitions/Viva-Texas-Rivers.html
