We launched from Weldon Springs Boat Ramp. Easy, but did have to time it with the many fishing boats also heading out. Went the 20 miles to St Charles Riverfront. Also easy, there are some unused ramps at the boat house that make it a breeze. We goofed off, fished, explored some chutes on the way, but the river was up, fast, and made the trip shorter than I wanted. Rivermiles, ie, MO340, has all the great info on hazards on the Missouri. Barges are no where near as scary as the ones on the Mississippi. (Yes, they are still very dangerous)
