Creepy!

I got the creepiest email this morning from some perv that read my blog, liked my pictures and wanted to offer me a bit of fun!  I know it's the chance you take when you have a blog, but I'm still skeeved out!  I often think I should make this blog private so that readers have to have a user name and password, but I don't know how I feel about doing that.  It's something I'm seriously considering.  Thoughts?  Speak now or forever hold your peace...
