The wife wants to spend a romantic day the Park. Should I bring the
4wt along? If so, where are some good spots? Any ideas are
appreciated. Thanks.

I've flyfished both the water around 79th street, where they rent the
rowboats, and the Harlem Meer. Caught small bass in both places.
Generally worked the southwest shores of each body of water, with good
results.

It's about what you'd expect: more novelty than for actual quality
fishing. But then again, I'm not a big fan of still water fly
fishing, regardless of the location...
