What I liked the most when I went to the Dominican Republic is to see that the girls loved my hair because most of them had very frizzy hair, it was almost like an obsession they had with caressing my head. And they all tried to speak English just to sympathize with me.
I don't think it's a weird name, are you crazy Sirgay? in my state there is a mountain with that name.

I think in Spanish it is a very common name for places.
