• Tackle & Baits

  The rules here are undocumented as far as public sources go. The nearest car park we can see is half a mile out, so expect a walk with your gear. A campsite is mapped about half a mile away, which makes an early start easier. Toilets are half a mile away, which matters on a long session. Parking is often the real limit rather than the bank itself. Check whether bait restrictions apply before you buy any. Finger Lake, 2.6 miles away, makes the obvious fallback.
