Guys: Walmart has a "trac(k)" phone that seems to work similarly to a cell phone. Paul Harvey was advertising them for a while. Any of youns ever had any experience w/ these track phones? :thumbsup: or :thumbsdown: ? How do they compare to cell phones? I ask because it's good to have a mobile phone to stay in touch w/ loved ones & for emergencies (they can happen to anyone, any time).
