Oh man!
I absolutely second what Randy said!
That's a dog-gone big lake with lots of critters in it.
If the GF tires of fishing, lots of hiking areas, (LOTS!!!) and there MIGHT, I say MIGHT be an alpine slide at the ski slope or in the general area. You'd have to check.
If I went, the fish wouldn't bite that day, so let me know when you go and I'll stay away.
Anywhere along the Potomac River will work, chickie livers work great for the Kitty-Kat Fish.
Before you buy a dingie and motor, go explore.
You may find an area that you can easily get to on land or canoe.
Several of the lakes prohibit gas motors!!!!
I throw the kayak in and go get a workout.
Well, I don't catch any fish, no one on the lake does when I'm there.... LOL!
Oh yeah, never, NEVER buy a two-place kayak.
Quickest way to ruin a relationship, rent a couple of 'em and go play.
If ya like it, then buy TWO.
