Always have your favorite photos on hand to show in Zurfer. If you create a set in your Flickr photostream named "Photo Wallet", the photos in the set will automatically be displayed under the Zurfer channel "My Stuff".
Zurfer gets your location from ZoneTag (see 'Zurfer and ZoneTag' below). ZoneTag can often recognize your location using the cell tower your phone is connected to. If that's the case, Zurfer will automatically set itself to that location and show you the nearby photos. If not, try telling Zurfer where you are under "Options".
Well, Flickr has tons of geo-tagged photos but sometimes you boldly go where no photographer had gone before. Take a photo with ZoneTag - make sure you enter its location - and leave a mark for the future Zurfers.
