Abstract: The integration of the gravity and intervening-opportunities model in the recent paper by Gonçalves and Ulysséa-Neto provokes interesting questions on the role of the number of intervening opportunities on either decreasing or increasing travel. In this note I discuss such issues, as well as making comparisons with recent innovations in spatial interaction theory.
