I can get up there as early as I need to to make it work, but I didn't want to go too early and freeze my ass off.
At lower water, about 2'-2.5', I know it takes us about an hour and a half to run bridges if we take our time, but I think the water's moving fast enough now that bombing through it at this level would take about 20-30 minutes. I was figuring on about 45 minutes for a bridges run, so that leaves a moderate amount of time for playing if I get on the river at 8am. I have to be at work at 10am, so that's my time contraint.
Sounds like you've got most of your day, so I'm not sure if it would be worth it to you to go up for just one run. I'd be happy to shuttle you up for a second one though if you want to run it by yourself.
I'm planning on heading up tomorrow about 7am to see what the traffic is like and do a run if I can. I'll have a better idea of timing after that.
