[Az-Geocaching] Question about Event Caching

[Robert & Linda Smith]

Can someone tell me in 25 words or less how to set up an Even Cache??  I 
have seen several posted in different places and the couple that are 
near me are on days when I have something else going.  Trisha told me 
one time that if I wanted an Even Cache at a time when I could get there 
was to plan one myself.  I just don't have any idea what is involved.

Thank you,  Bob Smith,  Team Petite Elite
