Whats the launch like? How far would this be from where everyone meets up?
Whats the water like? I have never been to Parker
Launch is OK
It's a few miles up river, cruising speed 15 minutes or so plus the no wake zone.
Google it to see their website.
Water between Road Runner & Bluewater doesn't have many issues as far as shallow areas. Above Road Runner it's good to know where the channel is, follow someone in the group the first time you go up. It's not difficult to see it in my opinion.
The pic in my avatar is at La Paz 3 spots up from the launch ramp
