Hello, my friends and I are planning on making a weekend kayak trip, and want to know if its practical. We are leaving from Corvallis, OR on Friday about 9:30 PM, and want to make it too Portland,OR by Sunday afternoon. We know its gonna be rough, but we think we can make it. Non of us are very experienced kayakers, but we're pretty athletic, and are planning on doing a lot of paddling to make it in time. We're planning on taking sleeping shifts during the night and staying on the water. We're gonna go on land for the waterfall, and walk around it. Do you guys think this is possible? And do you have any advice? Thanks for the help.
