We desperately need new blood. If you like outdoor activities in areas where cell phone coverage is poor (camping, hiking, skiing, dense urban gatherings) or enjoy the idea of having unique access to spectrum for learning and experimentation, you need to look into amateur radio.
Some choice projects:

I'm an extra working on developing classes for introducing modern radio to the next generation of hams. Feel free to ask about anything.
