Just Another Day at the Beach
Ah yes, Americans with their puritanical outlook on life. Europe has a lot of topless beaches in many places. Clothing optional is practiced at many beaches, some countries more than others. It's only the Americans that say, "I don't want to see that". Great! Just look the other way and let others live how they wish.
Been to Wreck Beach in Vancouver, Canada and it is very pleasant although the season is too short. Since it is right next to the campus of UBC there are many younger people there.
Have been to Sauvie Island in Oregon. A good place but again the season is too short.
