I was talking it over with my wife and it would just be me and my 6yr old son. Wifey and our 2 1/2yr old daughter are going to skip going. Any chance the rest of your group would be showing up earlier? It would be pretty late to get there at 2pm+, and still have to run the shuttle and gear up. If the rest of us could get there earlier, say 9-10ish, we could all run shuttles and maybe even launch from pumphouse. That would make the fishermen happy and we could all agree on a campsite to shoot for. Then you could pull in at 2, rig and just launch from radium and find us at the campsite already. Getting out early on Sunday is just a matter of getting up and breaking camp early on Sunday. Even from Bond, I can't see it taking more then a few hours if you are motivated to row.
I would like to camp at the treed site beyond the twin bridges, but the sites farther down stream are also BLM cattle grazing areas. So biting flies can be a problem there. I do not recall any sites between Bond and the twin bridges. I looked at one area near the ranches that had potential, but I suspect that is not public land.
