Pawpaws are awesome. Go try to find them around April. The flowers are easy to identify. Once you know what a tree looks like, they are super easy to find year round.
If you live somewhere on the eastern half of the US, and you have an overabundance of deer, you probably have pawpaws around. Deer don't eat pawpaw seedlings, so pawpaws have a competitive advantage in eastern US forests devoid of predators.
