Fixing My Rack

Finally got the car rack put back together. I had to take a trip down to the store and ask for help. It turns out there's a hex wrench adjustment that needs to be made. Once that was done (and it took a bit to figure out how that worked) the racks are on nice and tight. I'm going to experiment with a little trip onto the American River at say Howe or Watt and then go up and then down. If I'm right, there won't be much current and I'll have no problem. If I'm wrong, I'll have a short paddle to some current area and then have to turn around.
