When I had a big handcycle (which was stolen a few years ago) I would park near the restroom, lock my bike up, and have my boyfriend carry me into the restroom. We'd just use public park restrooms, which aren't always the greatest, but...
Now that I use a Dragonfly, so I can just pop it off my chair and head in to the restroom. It's pretty nice for getting around town and stuff as well.
This is one of the times that I appreciate that I now have a mitrofanoff, though, as I can be like one of the guys and just pull up behind a bush (this is what I do when kayaking) if I'm not near a restroom.
