We where on the Main in 2017 also and the ranger that checked us in asked that we not stay at Bargiman camp or the camps right before it because the fire fighters were staying there fighting the fire but told us they couldn't stop us from staying there. When we got there nobody was around and there where tree stumps still burning. The fire had jumped the river there. We ended up camping there and watched the fire burn up the hillside across from us the whole night. It was kinda eerie and the smoke was so thick you could barely see 50 feet up or down the river. Once we got past that area the sky cleared up and was clear as could be.
