I believe Chris Short is "tbonerocketeer" here....
Watch out about "a couple of events". I went to NARAM-56 figuring it would be my one and only....and last year wound up reserve meet champion at NARAM-60 and am in the throes of building and test flying models for NARAM-61 even though it will take me four days to drive there.....
Oh and yes, as noted above, pads and power are provided. At NARAM-60 launch rods of 1/8, 3/16 and even 1/4 inch were made available but if you want to use a tower or are using pistons, or both, you need to bring your own or arrange to borrow from other competitors. Any specialized launchers for, say, boost gliders or rocket gliders are also on the contestant. My own flying at NARAM-60 was partly on the provided rods and partly out of my own towers (The Apogee one and a simple one especially for my B Cluster Altitude models).
The actual process of flying was new to me my first time (though they also use it at the TARC finals, not surprisingly). The pads are numbered and you are assigned one when you check in for the flight. You go do whatever you need to prep the model to be ready to fly (though you may be asked to step back while someone is being launched from an adjacent pad). When you are ready you pick up the paddle that's on the ground with your pad number and hold it up so that the LCO can see it. You will then be "in the queue" to be launched and the model will be launched when its turn comes up.
