Hi Katie, Your post made me smile...and even feel a surge of "envy", even though I'm not a jealous person. What you did and are going to do is something I dreamed of...but I took a different path. I had my surgery when I was 15, and when I wanted to go off to Israel (kibbutz) for 6 months, my parents said no. (I had just gotten out of a back brace for osteoporosis and degenerative disc disease.) So they weren't going to let me go far. It seemed I was going to stay US bound, as long as I was underage.
But I made the most of it...I went to beaches, swam, used all those awful public smelly bathrooms. I went on camping weekends, changed in dirty, bee-ridden stalls, sometimes in the dark. (Bottles of water, plastic containers, hand wipes, and a flashlight—good planning made all of it easy) I was 16 and 17, and none of the other "campers" knew about my surgery. I just "disappeared" during social hours, or early in the AM, before anyone was up. It would have been easier if I'd shared the info, but except for one friend (who covered for me) I wanted to be anonymous.
Fast forward...20+ years...married, had two children & got divorced. I began to travel (a lot) with a friend in a single-engine plane. (no bathroom) We flew all over the country, Mexico, Canada, along deserted mountain roads, the Caribbean & even Haiti. Bathrooms in rural Mexico aren't so clean, but I managed. There were times I had to empty my pouch in the woods, so I dug a hole, and used tissues.
When that travel period ended, I headed for Europe (tours), and traveled all over. While Greece & China had flushing toilets, they were holes in the floor, and one had to assume the squat position. I stood up, to pee & empty, and splashed a lot...but I always carried toilet tissue with me especially in China. (where there is none—even in the cities) I've also been to Israel, Eastern European countries, to Japan, and to South Africa/Botswana/Victoria Falls. Ironically, I found some of the cleanest bathrooms in African tourist areas. But I always traveled prepared. At the time, my parents and even my doctors were concerned about traveling in Africa, because I had Hep C. It didn't phase me at all...as I wasn't going to sleep with anyone on the trip.
When I see documentaries, or news shows, about people volunteering in Africa... I get an ache in my heart. I felt that way in China too, when I met Americans teaching there. I suppose, I could have gone that route, after my divorce, since my sons were in college, and they were going to live with their dad when they were home. But both of them had IBD, and I didn't want to be far from them. And now...at 68, I have too many medical issues, to make it feasible to do it. But I'd love to hear more about your experience. Best of luck to you.
