Gunpowder River and other MD trout streams

Hello All!

I'm new to the site but wanted to know if anyone out there fishes the
Gunpowder in Maryland. I'm just getting back into this and any info on
good spots, what to use, or technique in general would be greatly
appreciated.

Also interested in trying some of the other local trout streams if you
have any suggestions.

Finally... know any good spots for stream Brookies near Baltimore? Any
of the streams in Northern Baltimore county worth trying?

Thanks
