Thanks all for the tips and support! Yes, I could try angling the bag outward, especially with a larger bag that might work well. For everyday I angle towards the center (easier using standard toilets) but I can twist it outward while riding. Now why didn't I think of that? Thanks! Forecast is looking better than feared for this coming weekend, so I'll try for another practice ride then and see how that works. The idea for a valve is also growing. Sure wouldn't be ready by March, but maybe I'll sketch it out and send it to the folks who produce the supplies I use. Then if it grabs 'em they can make me up a prototype to try out. As for diet ... bananas are good. And lots of water! (I'll have a camelback or the like along, I figure. Been following that thread to see what folks prefer.) No oranges, please. Also I'll stay away from stuff that day that sometimes goes down a treat and sometimes not, like nuts, or luscious tart hard juicy apples. But food is usually not an issue, so that doesn't have me worried. If there's any variety available, I can always find some that works for me. The recumbent idea has also occurred to me. But ... can I really face learning to ride a bike all over again? As compare my most memorable bike moments on the intro site ...
