Disabled Cachers... in Geocaching topics Posted June 28, 2004 My wife often geocaches with me, and she uses an oxygen tank due to a lung disease, and a birth defect in her heart. (and she's never smoked in her life) You won't find her registered as a geocacher here, for some reason she just won't do it. She says it's not neccesary, since she's always with me when we geocache, and I log the finds. I'm not fussing, I'm just glad she enjoys going with me! I'll sometimes refer to her as "Mrs CND" since she won't pick a handle. Our oxygen machine at home allows us to fill our own bottles. The portable bottles are relatively small, (12' tall) and each bottle will last a little over an hour. (set at 5 L/min, the highest setting) The bottle has it's own pack, that can be worn across the shoulders, or around the waist. I carry the bottle, and we have several feet of small tubing so she can stay connected when she's walking beside, in front, or behind me. We carry four bottles in the car or truck, and just grab one when we get out for a hunt. We live in the Blue Ridge Mountains, so the terrain can be rough some times. We just take it slow and enjoy the hunt, and spending time together. "Mrs CND"
