Acknowledgements

Thank you to all of the clients and co-workers who helped develop the strategies presented in this book. The wheelchair users worked through many of the navigational problems and helped to come up with viable solutions; they are the true authors of this work.

Special thanks to Janet Barlow, never just a boss, but also a mentor, friend, and believer.
