I've been birding since 1977. While my interest in birds has taken me to many exotic places in the world, some of the most enjoyable experiences have been right here in the San Francisco Bay Area. I teach an Advanced Birding class at the Palo Alto Adult School.
I love the graphic on this shirt, but "even as we speak" doesn't do it for me - I guess I get it, but I think it misses. I've looked all over for a shirt that says, "Let's go birding!". Would you think about doing that caption on the "speak" shirt? I think it would be more appealing to most people.
Your graphics in general are very nice!
