Let's see now. In creek bottoms check around Sycamores and Red Birch. In the deep woods look under Ashe. In the woods in general Ashe, big sick or dieing Elms, Poplar groves, Wild Cherry.
Something I've noticed that happens to me when looking is that it takes a while to "get your eyes right". Don't look right at your feet while searching, look out ahead to around ten yards and they seem to show up better. There have been times that I covered an area and not found anything and on my way back found them because I was looking out in front of where I'm walking. Shoot, I've even looked and set down to take a break and listen to the nature and then there they are right in front of me.
Once you find one they generally start showing up.
