I am fairly new to coding and need an expert's help. I just changed out a graphic on the site I manage and now there is a mystery line that looks like a horizontal rule. I cannot see where the error is on the page! Could someone please take a look at www.boojum.org? Between the logo and the header statement (the chalkboard graphic) there appears a line. Where is it in the code? What did I do wrong?

ANY help is very much appreciated!!

Thanks, Robyn
