Here’s
how it works:  All eight of us guys (and sometime a bunch more), pile
into the back of a pickup truck.  We grab all of the squirt guns, water
pails, and at least one large trash can or bin we have previously
purchased.  Make sure everything is loaded with water and then head out
to the middle of town.  First thing you do once you’ve made it in town
is stop by a person who is selling large chunks of ice and proceed to
buy at least two.  Stir the large can or bin that contains the water
and ice and then drive slowly down the main strip squirting, throwing
water, and jumping in and out of the bed of the pickup.  The street is
so congested that the vehicles just crawl along while people are
throwing water everywhere and laughing.  All along the way there are
stations where people are filling back up on water and buying ice.  The
Thai people also like to come up to you and gently smear a mixture of
flower and food coloring (and sometimes incense oil) on your face. 
After a few hours of this you get pretty tired, but it has been quite
the experience and a lot of fun.
