bring a video camera for all of the drunks on the river, a cup holder for yourself, and a lot of turkey sandwiches...don't need a waterbottle or first aid kit...if you get cut put your injury in the river and you can drink the river...the river has a high enough alcohol content that it disinfects all cuts and kills all paracites...but then that would eliminate the need for a cupholder...(disclaimer:the above is just a joke...if you are stupid enough to drink the river or put your injury into it and you get sick then its not my fault that you don't know how to take a joke)
