I second everything Equestrian Mom said. I empty my usual way even in public (sitting far back on the toilet seat so there's room to empty between my legs) but I think I got over my squeamishness about
sitting on public toilets from having to use public toilets about
10000 times ;)
If you haven't ridden in a car much yet you might have some trouble finding a comfortable position for the seatbelt across your lap relative to your stoma and pouch. In the early days I used a small pillow or just wadded up my jacket to cushion things.
Finally, regarding velcro pouches... many appliance systems have pouches that are exactly the same except they have velcro closures instead of clip closures. For example I wear a Hollister 2-piece (same thing they put on me in the hospital), but as soon as I was discharged I switched from the clip bag to the velcro. It is SO much easier. Also, *while I was in the hospital* a nurse was showing me how to use the clip and it came apart in her hands!!! I never wanted to rely upon a clip again!
