I appreciate the concern, we are apprehensive as well hence joining the forum and making this post
You should be very apprehensive. A one-boat MFS trip is not a good idea at high water, not to mention that y'all are likely to be launching on Marsh Creek which has it's own set of hazards, and there's Dagger Falls. Just out of curiosity, when you were putting in for permits on Wreck.gov, after you'd put in for the Smith, did you just kept clicking when it offered you the option to put in for more permits on rivers that you'd heard about but have no idea of the character of those rivers, but just put in for those permits on the chance that there may be some good fishing?
Do you realize the fishing will probably suck because all the trout will be hunkered down waiting out the high water and that the trip you've won will likely be balls to the wall serious pucker factor, hope not to die, possible snow or rain, gigantic trees flushing down the river with you for every day of about 6 or 7 days? Do you realize that you've deprived people with the equipment and experience to undertake this river trip, that are raring to go even (or especially) above 5.5 feet, who may have been trying for years to get this highly coveted permit, of of being able to go because you didn't know what you were applying for?
Just curious.
