I have to admit, I too got started by watching and asking questions. But I got started by watching at the track, and because it was the track, I only asked questions AFTER the driver was done running. I didnt get in the way of the RCs because only the turn marshals were allowed on the track, I didnt bother the drivers while they were driving or while they were in the pits because again, only the drivers are allowed on the platform, and I was respectful of the pitmen when they were busy prepping their RC for the next race.

This is something kids have no respect for out when bashing up and down a field or open parking lot. They pester you when they need to simply sit back and watch and then wait for the proper opportunity to ask. I would have no problems with that, but unfortunately, the kids I have come across always want me to do stupid crap. A kid the other day asked me to race my RC down the street against him on a bike. That is a no-no on so many levels. The RC I was driving was a gasser which is a big RC to begin with. If it went in front of him or he turned and his front wheel went over it, it would have been bad news for the RC, but potentially life threatening for the kid as he would have tumbled off of his bike and possibly hit his head on the way down.
I told him "no" to about his race idea and packed up and left. He might feel I was stuck-up, but again, I do not want to endanger a child.

I sound like a serious sour puss about this, it's just that I have had too many kids ask me to do stupid stuff that I simply wont tolerate it anymore. And I am not packing up my gear to be a jerk, I know how kids are. They ask and ask and insist to the point that you have to either be stern and say it is unsafe or simply leave. I choose to leave because I seriously think yelling at a kid is not the right thing to do.
