How do you check to see if/where you have a vacuum leak?

just what the title says...

i have some reason to believe i have a small vacuum leak... anyone know a good easy way to check?

i really don't wanna bring this thing to the dealership and pay a $70 diagnostic fee... then a bunch of work that i probably didn't need.

thanks

Get a spray bottle with water in it and lightly mist around where you think is leaking, you'll see the mist get sucked inwards if it's leaking. Remember to lightly mist above it, dont' go right upto the part and just spray it.
