Is there some group of people that like to go around and jump from rooftop to rooftop like in the movies?
It would seem to be some sort of extreme sport. “Roof Jumpers” might be a better name, but then that sounds too much like you are jumping OFF the roof. This is leaping from roof to roof–whether it’s with a leap, a handy rope, or mabye or even a spidey web.

oh yea! i saw a special on that about a year ago. The movement started in London. It is cool.
i believe that chimney sweeps do this. for more information, watch “Mary Poppins.”
There is a group who go around and jump into things and through the smallest places without getting hurt. Look up “parkour”.
