In Sydney's north, Narrabeen Lake is circumnavigated by a popular footpath / bike trail, a short section of which is built on a pleasingly-curved bridge. I decided that it would make a grand place for a star trail image, with the bridge itself picked out by bicycle light trails, choosing a moonlit night, so that the scene would be pleasingly illuminated. I didn't want to do this early in the evening when cyclists and walkers might object to my tripod being set up astride the walkway. So the trip was made late at night, with my own bike on the car, and cycled back & forth in the scene to create traffic, having to cycle directly under the tripod as I went. It's the first time a picture required me to bring my camera bag, a tripod, stepladders and a bike! No one else passed for the whole period I was there (about 3 hours).
