The waterfall was closed on my Maple Creek hike and I'm still annoyed

How come stuff like this always happens when you're really looking forward to it? I once drove two hours to a state park and forgot my hiking boots, so I hiked in sandals like a total goof. My feet were blistered for days, and I felt so silly. At least you were prepared, but that tiny sign after all that effort is just rude. Why don't they warn people online? Makes me want to double-check everything now, but it's still a letdown.
