BJJ and surfing connection?

It seems like a lot of guys who do BJJ also surf, not just Brazilians but
the American BJJ guys also. What is the connection here?

Lot of BJJ in SoCal.

I used to surf way before I knew about Jiu Jeetz. But now Im in El Paso...

Chaka Aboo Ganza!

Because Surf Is Kinglyon!

Rio is a popular surf spot in South America.

Rolls, Rickson, and Royler were very good surfers from what I've read.

Ba,Ba Dip-da-Dip-da-dip!

because in surfing, like zoo zhitsu, you have to flow wit da go, my frien...

I, however, fear being eaten by sharks, so I snowboard. ;)

Most of the bjj is on the coasts... theyre originaly from the tropics so... do the math
