I don’t think you’ll have to worry about being sold out of minnows, they have three tanks full right now, plus a scheduled delivery coming.
The bait shop opens at 6 am and the ramps are always open. Some folks like going out earlier and slid $7 under the bait shop door while others pay when they come in.
I’ll guess if the weather is going to be in the 30’s on Friday, there will be boats launching around 5:30 while most will be launching between 6:30 and 7:30.
It flows pretty smooth even when it’s busy.
