Pretty sure that Uppers has been run at 5 feet +, but that was back in the day when the gauge got over 4.5. Recently and since Whiteline changed I think the highest it has been run is around 4.25. And no nothing major has changed in Lowers, a few rocks have shifted here and there but over 3.5 it becomes pretty serious. Some days I'd rather run Uppers at higher flow than Lowers. Long, fast and furious. + you are getting old. Even older than Gary E.
Looks like the clinic is on, bring whatever boat you are comfortable in and come ready to get your boof-on. I'll be up there around 5pm. If you have a bomber roll come and git sum.
