Documents
Proof of Identity (Drivers License or comparable: Game wardens sometimes ask for proof-of-identity.)
Fishing License (New York or Maryland)
Personal Items
Hat (preferably a ball cap)
Field Rations (a.k.a. on-the-go hunger-fighting food that suits you)
Privy Bag (Sometimes a lavatory is close by. Usually though, you have to find a tree and Boy Scout it. Therefore, bring a zip-lock bag filled with a little TP, decomposable sanitary wipes, hand cleaner, etc.)
Individual-Specific First Aid (things like an epi-pen, insulin, etc.)
Conditions-Appropriate Clothing
There is a Swedish maxim that blue-eyed mothers drill into their blonde-haired children: “There is no such thing as bad weather, only bad clothing.” Firstly, wear items made of either wool or synthetic fabric. With the exception of Ventile, cotton fabric is a set-up for trouble (The absolute worst clothing is made of denim, which is a cheap, loosely spun and woven twill that sucks-up water as if it’s going out of style. Personally, I never wear jeans for this reason. The stuff is garbage.). Secondly, no matter the weather, bring a reasonably waterproof jacket that can be worn while wading. Thirdly, wear wool socks with polypropylene undersocks (Go heavy if the water is cold. Please text me prior to your Mad Day Out if you require guidance.). Fourthly, think in terms of layers. Air temperature may be 65-degrees Fahrenheit. Even so, if you are wading a river where water temperature is 49-degrees, then you will need to wear a polyester base layer and potentially insulated trousers (Again, text me if you require guidance.).
