I'm itching to tie some flies and get on the water. I'm in Rhode Island, and right now I can either wade a river or fish a pond on my kayak, since the temps have been a few degrees either side of 42 for quite some time. I'm looking for trout first, but I'll be happy with anything at this time of year.

Two questions, then:
A. What should I tie?
B. How should I fish it? (Especially in a pond)
