Cedar Hill State Park has the BEST BLUEBONNETS in my opinion! Maybe i say that because i LOVE Cedar Hill State Park....Or maybe they just ARE! :) They have a big open field with them that has gorgeous backlighting. Its at least A FAVORITE of mine for sure! Cedar Hill State park is another huge place that i haven't even see everything at yet. My favorite area is Penn Farm for this open field and great old barns! Its perfect for family sessions, seniors and so much more! I Love it because it gives my clients lots of variety.
