Absolutely, but there are two types of the bag webbing. Sad thing is you can't tell till you feel it. If it's super-silky then it isn't the good stuff. You want the kind that feels a bit scratchy like polyester threading so it stretches and doesn't pull apart. (I think most places carry the good stuff, but the silky crap pops up occasionally)
I make it a point to put out our webbing by the end of September so it gets rained on, twigs and trash blown into it and it gets yucky and MORE realistic by the time Halloween rolls around.
At the most, you might have it stretch out a little from the weight of rainwater, and have to pull it tight and re-anchor some of it. I put it up HIGH so as to accommodate this stretching, so we have minimal damage control to do.
