Answers to some questions:

I am on a towboat (80' x 25') pushing 2 loaded jumbo petrochem barges (600' x 54'-strung out). Loaded upbound (680' x 54' x 9') and empty downbound (380' x 108' x 2'), not counting the boat's 10' draft).

These adventurers need to check for traffic before crossing sides of the river. Down bound tows move at 10-20mph. They can call for help, if needed, on ch 16.

ALL boaters need to know about the Rules of the Road, and very few have a clue!!

The bicycle flag is a very good idea, IMHO!!!
