I walked 10 miles today. I started south on California Ave to Erskine Way. Walked down Erskine/48th to Beach Drive. From there after a mile i met up with my parents who walked with me to Alki and then departed as i continued walking Alki/Harbor Ave to Avalaon Way then up to my house.  At a small park on Beach Drive my parents and I came upon a stone tablet painted with white stripes for tic tac toe, with smooth rocks with painted X's and O's. For the record my dad cheated lol. Here are the pics.
