Well, more than 100. Just because they didnt show up at the website doesnt mean it didnt make an impact on the hobby. When I went to my local hobby shop to buy a rocket kit (my first kit in 2 years, thanks to the discovery show.. I'm a BAR IV) the store owner said he'd had people calling and popping in like crazy, all to buy rockets after seeing the discovery channel rocket shows.
I still havent been to my local launch because I dont feel like I have enough rockets to make it worthwhile. Maybe next month I'll show up with 3 new rockets.
Yesterday I core sampled with my new Icarus (glue wasnt completely cured on the centering rings) and my buddy lost his Alpha III after a high alititude "experiment". Heh. What a blast! Today we'll try the Icarus again.
So yes, the show and the commercial have made an impact... but you have to give time for the spark to turn to fire.
