If you're not familiar with the Tech Tee T-shirt, you should be. (These T-shirts also go by the name "Dry Fit"). Instead of cotton, they're made with a polyester blend. The beauty of these shirts is that they have the ability to wick away sweat from your body to the outside of the shirt where it will evaporate. Athletes like them because they'll keep you warm and dry in the winter and cool and dry in the summer. Why do I like them so much? Because they're great to sleep in. The slick polyester material will allow you to roll and toss in bed without the shirt getting bunched up like a regular cotton T-shirt will. And, if you have night sweats, it will wick away the moisture. You can find Tech Tees at most clothing stores in their sports department.

A couple of weeks ago I reported that you can still use a deactivated cell phone to make 911 calls. Wanda Shell e-mailed me with an addendum to the tip. She pointed out that if you're on a 911 call with a deactivated phone and hang up, the operator won't be able to call you back. Good thing to remember.

There's a phone scam going on in North Georgia that you need to be aware of. Criminals are randomly calling people out of the phone book claiming that they're with a local bank. They say there are problems with your account and you need to confirm some personal information. If the criminals get lucky and you actually use the local bank, they have the opportunity to rip you off. Bottom line, if any supposed organization calls you asking for personal information, you should be wary. Call the organization directly before you give any information out. It pays to be paranoid.

Whoever invented the baseball cap with the LED lights built into the brim is a genius. I use mine all of the time. There's a new model out on the market that I really like. The brim not only has LED lights pointing out, but it also has LED lights underneath the brim aimed down. In essence, the baseball cap has high and low beams just like your car. This is a great feature, especially for fishermen who need light shining on their hands. You can find this cap at panthervision.com.
