Connection in San Salvador, can I leave the airport and do some sightseeing? [closed]

I am travelling from Montevideo, UY to New York.

I have a connection in San Salvador, I arrive there at 1.30 pm and the flight to JFK leaves at 7.45 pm.

I have the B2 tourist visa to enter the US. 1) Am I allowed leave the aiport? 2) How far is the aiport from something worth going?

Thanks
