Alot of the ones we had were sunrise starts when possible....others could be tide dependent with the time to launch being later in the morning. Mid Summer an early start is a must due to the heat so there are many things to consider when I setup a "Scramble" but thats just me. The North River "Scramble" we lucked out to have the tide coincide with an early morning launch.....we needed a dropping tide for that one and it lined up perfect with an early start! We will be doing a few night time "Scrambles" though!
