There is a spider in my back yard that is rather large...
it has a black body with yellow down the sides with yellow dots, and brown legs?
Just wondering what kind of spider this is if anyone knows...

Thanks

I'm looking for a specific game that was spread around the net between 2000 and 2004. It asked you specific questions such as family members names and birthdays. Then, it had you do something like add up the numbers from letters in their names and the birthdays to spell out a new name. That new name would ALWAYS end up being someone close to you like your first major girlfriend or boyfriend. Does anyone know where to find this?

A group of four students wish to cross a bridge without side rails in the middle of the jungle very late at
night. They have one lantern to share. No one may take a step without holding the lantern (it's dark at
night with no moon). No more than two people may be on the bridge at one time, not even for a
moment. When two students walk together, they must move at the rate of the slowest person. What is
the shortest time it would take for all of them to get across? Use the following information to solve the
problem:
• The first student, Joe, can cross the bridge alone in 5 minutes.
• The second student, Torey, can cross the bridge alone in 10 minutes.
• The third student, Sarah, can cross the bridge alone in 20 minutes.
• The fourth student, Mike, can cross the bridge alone in 25 minutes.
