Ik roei, speel met kleine zeilbootjes #df65 of mijn #SpringerTug (beiden #rc) en soms met taal.
Fan van #linux (al ben ik er nu wat minder actief mee bezig). En als trouw luisteraar van #damnhoney zou ik me bijna #feminist kunnen noemen.
Sinds kort speel ik weer met een fototoestel. Resultaten zijn te zien op https://fotograaf.van.petrafenijn.nl/
