A reminder to readers that you may be interested in checking out RTS - Regional Turboprop Spotter, which now covers most all turboprop aircraft from about 10 seats +. The same type of information and photos as your TwinOtterSpotter, just a wider subject matter. Of particular interest to some readers may be the inclusion of the Cessna Caravan type, where I don't believe there is any similar detailed web coverage elsewhere.
