Field with wildflowers

Hey everyone,

I am trying to find an area with wildflowers. I know most of the big fields bloomed already, but I'm hoping there is an area around still. I've been driving around and there are some okay-ish spots l I've seen, but I can only drive so much. And I've seen enough to think there is still some hope.

It has to be accessible to the public, as I want it for a secret proposal.

P. S. Don't tell my girlfriend. ;)
