I met up with Mandy and Mike (LDREBEL on the R6).
We went through the loop a couple times. The weather was great and there wasn't much car or bicycle traffic. However, there was a group of kids walking through the loop that made it a bit scary. They felt they could walk in the middle of the road, even their adult supervisor didn't see a problem with that, since he was in the middle of the road too.
Luckily I don't speed too much through there so didn't have any close calls.
