Because my other hobby is geocaching, I'm used to walk with my GPS. Since half of 2008 I found a purpose for my GPS logs: openstreetmap! My main contributions can be found in the region of Nijmegen and Enschede in the Netherlands. I focus on cycle routes and hiking tracks in the forests around Nijmegen and Enschede. My activities can be seen at hdyc.neis-one.org.
