Bukkerittet
Three weeks ago, I added several trails, mountain roads and lakes at Skeikampen, and now
I did some minor cleanup and collected ways that are part of the mountain bike competition "Bukkerittet" into a relation:route.

Farmland adjacent to Fredrikstadmarka
Finished rough tracing based on Landsat imagery of farmland adjacent to Fredrikstadmarka,
e.g. the area between Fredrikstad town centre, Veumveien, Evenrødveien-Seppoveien,
Elindveien, Solliveien (Rv.112), and Rolvsøyveien (Rv. 109).

Rød ringløype in Fredrikstadmarka
Added a few minor trails in Fredrikstadmarka,
worked on getting the relation:route for "Rød ringløype" correct (thanks to user dagbj),
and added marked_trail:blue for the trail connection from Rekustad to Hatten.
Still lots of marked_trail:blue and route:ski tags there that needs review.

Rough initial traces of trails and gravel roads at Skeikampen, Norway
I've traced several mountain trails and roads near Skeikampen and
used the lake walker tool to add lakes.
I plan on reviewing tagging and tracing of footways, especially near joints.
I miss SRTM data to render maps with contours for this area though.

Trails in Torsnes, Fredrikstad: Heiefjella and Thorsø-tangene
I spent a week in Torsnes outside Fredrikstad this summer,
exploring the last bits of trails in Heiefjella and Thorsø-tangene.
I've traced footpaths based on over 30 tracklogs collected while mountain biking
there over the last three years.
The amazing aspect of user contributed maps is how accurate and
up-to-date we can make them. This spring they released a brand new map
of the area called "kulturhistorisk turkart" (historical hiking map).
The mapper obviously haven't revisited any of the trails recently (last 5-10 years),
as some tracks (what would have been tagged tracktype=grade4) are now
been overgrown by vegetation, and are hardly visible.
I also added woods for Torsnes, drawn after Landsat imagery and
corrected near GPS tracks of roads and trails, as well as from
memory of what the terrain looks like.

Trails near Fagervann in Nordmarka, Oslo
I've added a few trails between Hammeren and Fagervann in Maridalen/Nordmarka.
Data collected on a mountain biking trip of 850 meters ascent and descending some amazing downhill singletracks, by some bikers regarded favorite trails in Nordmarka.
