A Bike Roundtrip in University Forest

Today I undertake a bike trip, hoping to finally reach Mirador Lo Rojas, which I tried before in 20160423. Alas, it turns out again that OSM data about the woods behind my house is not precise enough. What one can learn perhaps, is that roads that look nicely straight on the map do not exist in reality. Please note that my path crosses private terrain, and I needed a nice person to open a closed gate to continue.
