I think all tracks could go back to the full 1/4. Dom Lagana and plenty of others feel safe going the 1/4 mile at US 131 MSP. I did some work using Google maps and got the following measurements for each track and a few that are not on the tour. All measurements are from the 1/4 mile stripe to the start of the sand or major curve/turn in the case of a few tracks.
