You know how Spider-man travels throughout the city by swinging from web to web? Well, Here's the following reactions that I think the people in the city would have to it:

1. Viewed as a form of vandalism. Business would hire janitors just to clean up the leftover strings.
2. Various Baddies could collect the webs and analyze its molecular structure to figure out how to defend themselves against it more efficiently.
3. People would collect it for one of two reasons:
a. They'd want to keep it as a souvenir.
b. They'd want to sell it on ebay for others who'd want to keep it as a souvenir.
4. Spider-man would get the pants sued off of him. (You know you were thinking it. XD)

So, how do you think people would respond to the webs Spider-man leaves lying around? Please feel free to leave your opinion in the comments sections of this post! :D
