Actually, front yard bird watching. I like to sit in my sky chair and take photos while they eat. I've been known to disappear for an hour or two at a time just to watch the birds. I have to admit, it's a wonderful way to relax. Not to mention I've been experimenting with my camera in an attempt to improve my skills.
I've also joined an online group that is helping me identify those that I haven't been able to on my own.
