Thanks, but I have several old film canisters in reserve (I loose small things sometimes). But, Glucometer stick canister is a great idea that I had not thought of. I'm with you on the small pocket knife - I have carried one since childhood and even though I never seem to find anything to cut in Africa, except the occasional apple or biltong stick, I likely will always have a small blade on me, no matter what continent or archipelago I'm visiting. Regarding the eyewear, The Almighty has blessed me hugely with above average eyesight and I should take better care of it than I sometimes do. But, I guess I'm just a greasy bohunk, because when marching over hill and dale with a rifle, I usually sweat enough to make glasses a slippery mess on my face so, I never wear them (sun glasses) unless riding in a car or on a mule, horse, etc. I have seen spitting cobras in Namibia but they didn't spit at me because I kept a long distance away. Otherwise for poking at them with a spoon or some such, glasses might be worth while.
