I had a guy blast mine with glass beads. Don't use steel as it will imbed in the aluminum and rust. Took him 10 minutes. He's a dustless sandblast company and he had a gantry crane to lift it off the trailer.
I guess I’m down the middle about it. I know plenty who went through it just fine and I don’t know how many may have had it and not known. But I know a few that have died and a couple long haulers. My wife is high risk so I really worry about her. I wear a mask.
One of the coolest things is going to that bird sanctuary down south. I was there my daughter for scouts. We got up close and personal with owls, hawks and eagles. Crazy how big they really are. https://www.worldbirdsanctuary.org/
Keep notes about flow when you go and it won’t take long to learn what is what. High or low relative to the median flow doesn’t mean the fishing won’t be good.
