The area we ride the most runs right along a section of the Missouri river. It has several little beach like areas with lots of trees where people can pull their boats up and hang out, camp, whatever.
Last summer, my son and I (mind you, he had just turned 13) were riding and it was towards the end of the day (6pm-ish.)
We come upon one of these little beach areas, which just happens to be at the beginning of one of our favorite woop sections, and what do we see?
TWO TOPLESS GIRLS RUNNING RIGHT AT US WAVING THEIR ARMS!

(Did I mention that I had a 13 year old "heterosexual" boy with me?)
Needless to say, both my son and I were completely stunned. I can't count how many time we looked at the girls, looked back at each other...looked at the girls, looked back at each other...without a single word...trying to figure out just when we rode into the twilight zone.
They came over with their g-string bottoms and naked tops (no tan lines...it was clear what they were doing.) They said they had seen riders come by and wanted a closer look at the motorcycles. As you might expect, we both were speechless...which doesn't really matter because the girls were too old for my son and too young for me. It was obvious afterwards they want to tease a couple unsuspecting guys because they only spent about a minute with us (which seemed like an hour) and then went giggling back down to the beach behind the trees.
Anyway, my son was the hero of his group of friends last year and still gets "ata boy's" from his them to this day.
I told my wife about and got the expected

That's the most interesting one for us so far.
