Franklin's Lake Party
 
A Lake Party, in a new Lake in front of Franklin home.
 

Is an evolution of this:  https://www.GTA5-mods.com/maps/franklin-s-Lake, I had created to do a  test on the water running and I took just a couple of moles to see how  it worked, but it was a shame to leave it that way.
 

Now with a little more calm, I added a beach, located new bar, a  floating platform for concerts, disco and islands, and created a mega  Party on the Lake.
