I doubt that quinine water still has enough quinine to actually be a malaria prophylactic but it's a good excuse for a good SG&T (Sundown Gin and Tonic).
Yes, caves, my other obsession (or used to be). I have even managed to combine sailing and caving by taking my caving buddies to the Abacos to look for caves. I really want to go to Cat Island in the bahamas to look for some deeper caves. I'd thought my caving days were over but now my 17 yr old daughter is seriously into it so in spite of the fact that my knees are worn out from caving, no way I'd allow my daughter to be alone with any cavers, true low lifes.
Ahhhh, bat guano, smalls and tastes like adventure (if you get over the histoplasmosis)
