Most of the fiddleheads I ever picked where in damp/ wet areas and along river banks. Those ferns you see in the woods like where your ramps are are just regular bracken ferns, you can get sick if you eat them. Look for the young ferns that are about 6" high, they'll be growing in a round clump. They'll be covered with a brownish colored husk, like paper. You want the ones where the head is still tightly curled together and NOT starting to separate or uncurl, they can make you sick. If you're lucky you may find a patch with literally hundreds growing. I found a patch like that growing along the Allegany river in Potter county. Goggle Fiddleheads to get some ideas of what to look for. Good Luck!
