Ah, come on guys, March to early April is Bluebonnet (and Paintbrushes) season. Find out where they're blooming, and take a drive. You can go to the River Walk or the Alamo any day of the year. There are many great barbeque restaurants. (In the Stanford area, Armadillo Willy's is similar to Texas BBQ)

April is getting late in the season, so you'll likely need to head north as the southern areas will have already peaked.
For those that don't know, the highway department and other organizations spread seeds out (the preceding September), so it isn't all natural, but acres of bluebonnets and Indian Paintbrushes are still beautiful. The highway department schedules cutting of the highway frontage areas to be just before the bluebonnet season and not again until after. (Oh, for those from California: Don't go blithely tromping about. Rattlesnakes and cars may not give you the right of way.)
Btw, I've already suggested to Texas that they plan for a great bluebonnet season for
April 8, 2024. I wanted to make sure they get it in their budget in time for a once in a lifetime picture.
P.S. Low angle pictures are the best for bluebonnets. These are great for pictures of family, esp. toddlers.
