I was wondering who was going to get that March 20th. Most likely you won't see motors until the last few days! True about not really needing a guide if you know the routine of multi-day trips. My first trip none of us had ever been down before, It added an element of mystery of not knowing what lurked around the next bend. Also all you need to do now is pay your money, you can turn in your final list anytime before you launch. You should have no problem filling your trip.
