My brother in law's brother went through Colorado's academy last Jan (06) and has been on the road since June. He loves it. And he went through at a rather older age of 38ish. He's got my brother in law wanting to join our highway patrol as an Auxillary trooper.
My best friend left a city PD to be a Florida trooper. He enjoys it as it encompasses everything he loved about police work: Pursuits, finding drugs, playing with radar and laser, writing tickets.
Short answer, give it a try. You may find you love it.
