There are NO 'good' snakes, and For Heaven's Sake it was a Cottonmouth - blast away!!! Got NO time for paddle-flippin'. And FWIW, I don't care if the snake's head is triangular or not 8^O
As for the 'day bag' issue (whether just your regular ol' daily purse, a murse, a dedicated messenger bag or backpack allocated specifically for travel), traipsing around Dallas is different for me than spending a morning training from Munich to Dachau, then visiting 3 more points of interest (museums, memorial sites, flea markets, etc) before returning to Munich for dinner before returning to my room. I may want to bring a travel guide, a camera, sunglasses & regular glasses (and perhaps separate reading glasses - grrrrr), some water and probably some kind of snack and/or some picnic supplies, and I practically never leave the hotel without one of my RS Hide-Away totes [great for consolidating many small purchases, provides great cushioning for delicate items (purchased earrings, figurines, small beer glass, etc)]. Even though I'm usually hot, if I'm out all day the temperature swing could be enough for me to bring a scarf/wrap at the very least. When it warms up I want that thing off of me! Same thing with a rain jacket or umbrella. If I'm expecting to do A LOT of walking, I might bring a second pair of socks (if I'm worried about blisters, heavy rain, whatever). Nothing like blisters to ruin a vacation.
As noted earlier, women's clothing (cut and style) usually don't offer much in the way of pockets - and we tend to look more like a greedy squirrel stashing all of the nuts than men do when they load up their pockets. Women (esp. in Europe) very often want to carry tissues to replace non-existent TP (again, most men don't worry about that).
If I'm walking around Dallas, a) I don't need tram schedules, train tickets, TP (usually), guidebooks, b) the car won't be too far away, so no need to carry everything I may collect or need for my entire day, c) I won't be picnicking, d) I won't be carrying a camera, and e) again, I'm probably driving to dinner. I just need some cash and a few credit cards ;-) ... AND my water bottle. Just don't tell Jo ;-)
