Thank you, Cheryl! Business cards and yard signs have been the biggest help thanks to Minuteman Press!

The poor birds!!!!! They keep flying into my windows now!!!! Barrett worked so hard to get all my windows clean...they hadn't been cleaned in years so I'm sure that was fun. He said we had so much dust etc. in our backyard screens from the lawn mower and neighboring farm machinery that it looked like someone literally threw dirt at the windows. So, yes...we are apparently disgusting. I sit and stare out my windows all the day now. I love me a good unobstructed view! Ok...granted...Barrett is my son...but that just means I'm pickier than the rest of you. And this kid...he's smart and kind and funny and thorough...a pleasure to have working at my house...well, just being in my life. Hire Barrett to clean your windows!!! He's the BEST!!! (Sorry, birds.)
