Well, just thought I would follow up on this topic. I did get the chance to float this stretch a few weeks ago with a few buds. (Cedar Grove to Round Springs 2.5 days)
Carrs Canoe Rental provided a car shuttle. They were friendly and professional. $50 for them to bring my truck back to Round Springs.
As far as distance goes, we didn't have any trouble. Like most of our trips, we averaged right around 1 mile per hour.
This includes floating/fishing with the current, stopping to fish, stopping to eat, stopping to sight see, couple swimming sessions, etc.
The scenery was great and the fishing was a little slow. I did manage to land a 15 in pickerel as well as a 17 in smallie, amongst several small goggle eyes.
The only down side to this float was the company. It seems like there were a thousand party floaters with us.
Drunk and loud was the theme. One group used their paddles as drum sticks on the side of their canoes and sang White Stripes songs. Actually they weren't that bad come to think of it.
We were also passed by several calmer floaters and some family kayakers as well.
I bet we didn't have more than ten minutes of seclusion during the entire 2.5 days barring the camp time.
On my next float I'll be looking for something a little more secluded.
