We revisited the Earth Day festival today, the largest in the Midwest. Crystal blue skies and a wee bit more warmth successfully brought the throngs out. We bicycled today, which was a good thing, because parking would have been impossible. There was such a long line of bikes waiting to cross Skinker and enter the park that we had to go with the flow and run the red, just to make that light cycle. I’m sure that played well with the endless line of cars that were backed up all along Skinker, but they weren’t going anywhere anyway, at least anytime soon. I’m seen here sporting the latest fashion in bike lids, a waxing crescent moon helmet. If I turn my head and give you the other profile then you can see the waning crescent. Creator Lynn Herzberger fitted it and snapped the photo. It was tough to balance it on top of my head. He was supporting ISDC 2017, the International Space Development Conference, which occurs next month, here in Saint Louis. As part of their promotional effort they were touting Saint Louis engineering firsts: The Eads Bridge – First bridge across the Mississippi; The Spirit of Saint Louis – First nonstop transatlantic flight; Fabrication of the Mercury space capsules – First US manned spaceship. I’m not sure how much all of this has to do with Earth Day, but it was a lot of fun posing as a moon man and it has to be more relevant than rain gutters and replacement windows.
