Welcome to the BB.
If you want a shot at trout, try Russle Pond - it's a state park just south of Lincoln NH and a nice place to stay/camp - it's car camping and reservations might be a good idea.
Also try Sawyer Pond, in Bartlett NH - a short hike to a trout pond. shore access can be tough but doable and the water's not THAT cold, once you get used to it.
Be sure to post a report when you get back.
