As a beginner, it is great to have a book focused on Pennsylvania.   The book makes me want to learn more about butterflies in our area. The fact that I managed to identify all my photos, correctly or not, is a clear success for this book. I have a lot to learn about how to watch butterflies but this book will motivate me to try. 

I grew up with the saying ‘there’s no poor weather, only poor clothing’. So what is good clothing for long sessions of outdoor summer birding?
