A couple years ago I got a late start and just floated from White bridge to Crossover, there was only 1 other boat on the river and it was a couple guys that were on there 1st trip in a DB and it was pretty obvious. We got to the take out around 2:00 and as we were loading the boat, here comes the other guys, I thought they were pulling out there but they informed us they were going down to Black Creek, this was in December and there was about 2.5 hours of daylight left, they assured us they would be fine and they had flashlights if it got dark. I'm assuming they made it.
