I haven't done any night riding, primarily for two reasons.

First, my glaucoma has severely impacted my night vision. My pupils are 'blown'- they can't constrict when facing bright lights and the glare from said lights blinds me, and then I it takes a few minutes before what little night vision I have left is restored.

Second, my town has a curfew of 11 p.m. and all of the parks that I'm aware of around me prohibit people from 11 p.m. until 5 a.m. And since the local trail system falls under the jurisdiction of the Parks Dept., that means they are off limits as well.

But I'd surely love to be able to ride in the early a.m. to avoid the heat...
