We passed the 60,000 milestone 
We do now have 60,335 routes for 1,279,365 miles in active systems.
Pretty amazing. At least one traveler has claimed travels on at least one segment of 37,605 of the 60,335 active routes. I thought this number might go down quite a bit by omitting unranked travelers (like freeway.list, beltways.list), but not too much: 36,583.
Expanding to active+preview, we are at 106,807 routes (!!) and travels are claimed by a regular user on some segment of 41,834 of them.
