OK. Got Sean's message and responded off list. I know Lawrence, and sent him a message going over our options. Here are our limitations:
1) The cold. Even though we're getting warm days, the water will probably be too cold to enter without waders. Water that's below 50F will get to you after awhile. Trust me.
2) Technically speaking, Maryland requires a scientific collection permit in area waterways. We likely wouldn't get it in time for the weekend, even if I apply today.
3) No colorful darters around here. Just dull earth tone darters.
Here's white I propose:
1) A microfishing trip to Pennyfield Lock on the C&O. Fairly short travel time, and it has a really colorful small sunfish species, Lepomis megalotis peltastes. Plus, if you fish in the riffles below the spillway, there are usually some interesting cyprinids: spotfin shiners, and creek chubs.
What would help is if there are any trout fishermen who could tie leaders on size 22 hooks, so there are enough to go around. I have some worm flavor Berkely Gulp left over from last season, which the smaller fish seem to like.
Or:
2) Go to Virginia. I would need to find a small stream close by, so as not to eat up too much time traveling. I'll ask Derek W. for a recommendation.
