While KLAS during west ops is pretty cool - my favorite (in a smaller craft) is still MTH - Marathon Florida - either direction - I do admit, knowing I'm in for some fun, fishing, lovely shrimp bisque and a fresh fish sandwich might add to the appeal.
River visual into DCA is indeed very nice

- and as a young lad, I've found myself sitting by the Potomac watching those aircraft approaching 19 and found the dramatic turn close in fascinating as well
