Walking around Geneva - Stunts at Baby Beach

So in addition to Geneva Plage (beach) where I am a member, there is also an open public beach called the Baby Plage (baby beach) where a lot of families with babies and children come out on the weekend. I have not done it myself but we've walked by there often and recently this is what was going on there....
Yes crazy stunt bike jumps INTO the lake!! NUTZ!!!
