As we prepare for our Great Loop adventure, we  spent many hours on  AGLCA website. What a valuable planning tool! We first got the idea to travel the full length of the Missouri river before we knew that AGLCA existed, so glad we stumbled on to their very informative site. We discovered the difficulties associated  with navigating the Missouri River in similar fashion one can cruise other rivers. The lack of marinas with fuel being the most difficult to over come.
