I was watching videos on you tube and some people own fire alarms like Systems Sensors and Simplex and stuff like that. Some have a collection of them. I wonder why they have them. I thought its impossible to have those in your home and only have them in buildings. I see these fire alarms all the time in buildings and schools.
Sometimes, but if it does you just show them and it's over with. It also depends on which type of detectors because airport ones can already see it since they take a heat file pictures of your entire body whenever you pass through them. At least most new ones do now days so they can tell what you have. I have mine pierced, my tragus, plus 3 in each ear and I usually don't have any problems. Belts, jean buttons, etc usually set mine off before my jewelry has a chance. And don't worry they won't make you take it out.
I think you better plan on eating crow. A BMX bike is designed for short sprints. Most BMX races are over in a few minutes, at most. In fact, the races are so short you don't even sit down. With small wheels, small gears, and an inability to sit, you are going to be way outclassed in a road race. You should beg, borrrow or steal a road bike before you get slaughtered. Hope this helps.
it goes through the whore detector
Take a cue from sound studios! Boards that are wrapped in batting and fabric are a great way to keep the noise level down. Good Luck! :-)
