Isn't this the loveliest picture of poison ivy you've ever seen! Adam took a lot of great pictures of the trip, and that is why you won't see any photos of him on this post. (Ooops, I have been corrected. Although the picture above is often mistaken for poison ivy due to the three leaves, it is really skunkbush sumac. ) (O.K. I've been corrected again, skunkbush sumac is the western variety, we have arromatic sumac in Missouri) I still think the picture is lovely.
