mine more challenging...nite swimming take a pepsi or 100+
bottle...without the label so its totally colourless except for the
cap.
then we find it. and we muz bring it back to the shore(side of the
pool). we muz wack the other people and hold them in locks to
prevent them frmo bringing the bottles back. damn fun but we have
scratches and bruises. but it was good exercise!
