I'll echo fizzaly's comment - 36F ?? If feels like a heat wave out there today. Storm's comin' or so they say, so the ride home should be fun.
Today was my first ride in with the newly replaced Supernova E3. The standlight/tail light worked perfectly, and the new "Terra Flux" asymmetric lens puts out a really nice carpet of light. It definitely lacks the distance illumination that the symmetrical lens offered, but does a much better job from 0-50 feet. I can see why folks use the two in conjunction with each other when the dynamo is robust enough to support both.
