I think June in Ohio is one of my favorite times.
Of course I'm making a generalization for all of Ohio, but around where I live (and consequently drive back and forth all over for work) Wild Day Lilies grown in the ditches on the side of every road. And they grow A LOT.
Nothing is better than driving with the windows down on empty back roads full of beautiful flowers. Except maybe getting paid over the IRS suggested mileage for it!
