Ken,
Have you had any success at Black Hills. I haven't fished Gunners lake, but i'm sure it's a decent spot. From my experience, All the little lakes and ponds around Montgomery County have decent sized bass in them. If you are on foot, I would also suggest fishing the smaller bodies i.e. golf course ponds, drainage ponds and ponds in the woods etc.. If you look at google maps, you can switch between map view and satellite view to see the water bodies and what's around them physically. I caught a three pounder in the montgomery village golf course pond on watkins mill rd. With a bumble bee pattern popper (with a fly rod). There is also a pond on watkins mill rd where the seneca creek trail access is (big radio antenna's are there.) It's a little bit of a grassy bushwack to get in close to it, but I have had friends in the past nail some lunkers in there. If I lived over that way, i'd still be haunting all those little spots. Also Clopper lake is pretty good, there is a good access point off Longdraft rd in gaithersburg. If you want to hit some small mouth, just point your car towards dickerson and fish the potomac, monocacy (mouth of monocacy road) and warm water access (at Dickerson Conservation park, on google maps) near the power plant. I think the C and O canal has some largemouth bass in it, however, many parts are stagnant. Also the mouth of the seneca creek can be productive.
I also started bass fishing recently. I just picked up a boat last weekend and have been fishing the Liberty reservoir. I found a box of discount bomber lure's at the frederick walmart and have been fishing bomber 4a type lures, also a berkly frenzy (red tiger color) that I picked up at a KMart in California. Had consistent success with all. The 4a's would be good for fishing from shore because they are buoyant and only dive a couple feet and have produced all my larger fish within 10 feet of the shore. Also all these lures have some green in them. The berkly frenzy has to be reeled in at top speed and I've only caught small mouth on it.
