One of the major events on the St. Louis photo calendar happens this weekend, The Great Forest Park Balloon Race. This year is the 40th anniversary. Wow - I showed up in this burgh for college 45 years ago and wasn't very aware of it until I caught the photography virus.
The actual race is today. The Friday night event is the balloon glow. They stay tethered to the ground but repeatedly fire their burners to make a spectacular show after sunset. Much more of last night's and today's events to come. Note the little sign on the balloon in the bottom picture.
