Ditto's Soarhead and Dan. Mercy sakes if no one can track your flight. Fly the flight, enjoy the time away from wife kids work problems and distractions. If thats too disconcerting may I suggest a two place machine. That way you always know at least one other person knows where you are.

I get the original intent of the post but geesh, we can do just fine without the tracking. As Dan stated, we did fine doing decades of xc without gps or Spots or cell phones for that matter. Spend your time flying more efficiently, staying out of trouble and making friends with the farmer or rancher who owns the field you end up landing in, you can call home then and you may make a lasting friend, get a good home cooked meal or have fun with the farmers daughter.
As for the "safety" factor, having been part of search and rescue and CAP for years, good luck. If you depend on them your already in trouble. All my long flights were out of Minden and. I knew I was on my own, period. A survival kit, my wits and decent decision making are the best tools for survival. Communications come in a distant second.
