Yes! Remember that we scan parks/campgrounds for you looking for open spots and cancelations to send you an alert when we find what you are looking for. While we cannot manufacture an open campsite for you, we can be your eyes and ears when and if one opens up.
If you do not receive an alert for a scan you created, it simply means that there are no available campsites that match your scan criteria. We recommend being persistent as there is no way to predict when a campsite will come available.
