weather

Because the rain would make the picnic cloth wet, make the people wet, and produce a sad mood?! This is not a math question, right, this is a math fourm please don't post these questions!

The weather forecast shows a 90% chance of rain tomorrow.
How would this affect your plans for a class picnic? Why? 

I'd go ahead and go on the picnic, but I wouldn't get too far from the bus in case we had to jump up and run.  Getting caught in the rain isn't too bad if you can get out of it real quick.
