I got certified in 1970 when I was just a lass. Been diving pretty regularly since (except when I was living in the mountains of Colorado...I DON'T do cold water, ever).
Rescue/search recovery diving is not that much fun, but better than sitting behind a desk, I guess. The first time I found a body by touch was too creepy to believe. But, that's another story. Your wife works in LE in NC? Anywhere near my location? Sounds like time for a meet-up as we have lots more in common than just horses!
BTW, where does the name "roller" come from? Never heard that one.
The name roller is what alot of the less desirables call CMPD officers in our area. They just spend all their time rolling around in their cars hooking up good boys and legit businessmen standing on corners selling their wears at wee hours of the morning. They also go with the classic " Poe- Poe "
The reason I was looking into getting my rescue dive stuff was just for the knowledge and learning a new skill. Plus with all the required training and upkeep of the certification I would have more than enough hours of bottom time to maintain my padi ( spelling?)cert.
