I think the subject line pretty much covers it.
One thing I have noticed is that if I go in and then come right out it usually doesn't stall.
Guess I should add it hangs up either direction, whether or not I'm using a light source.
Also, I have noticed some people doing odd things before running the trail like, foraging for dirt,
they also backtrack, once or twice, not sure if it's their workaround, just thought I would mention it.
Thanks
