I live with them, and I backpack in places where they are dense. Get an Ursack and tie it to a tree with your food. Then you can laugh at them derisively when you wake up and see that a corner of your Ursack has been chewed, possibly with a few raccoon teeth in the Kevlar.
But seriously, racoons (not to mention squirrels) laugh at your bear bagging. I have seen a squirrel take a 15 foot dive from a nearby oak limb onto my bird feeder, and I get racoons footprints on my roof. How they got up there I don't know. I have no doubt they can find a way down your bear bagging rope like Tom cruse in an episode of mission impossible. Either of them will make short work of your ultralight silnylon. My worry about keeping stuff in the tent is that they might try chewing their way in.
Ursack = useless for bears (unless you are happy with having all you food crushed into a powder), but great for smaller varmints. Mine has room for about a weeks worth of food for one, and weighs about 5 oz.
PS learn to tie it right as well, I'm thinking raccoons probably have some knot lore.
