Aw gee Mule ....... there you go , giving away the secret of Cresent Valley. I honestly thought I was the only one who knew it existed. Not really, but I have never encountered anyone else there in three or four trips into it. One of my favorite places in the Deam Wilderness (or in Indiana for that manner). It's fairly easy to get into (even for a one-legged, old fart like me) and there should be ample water available in April. Also, the Sycamore loop is hiking only, and we wouldn't have to worry about horses.
This would be a good choice, but I must admit that you have my interest peaked with Panther Creek. But hey, I'm easy anywhere will sound good in April.
