I love night riding, but don't really feel like the need is there for night vision goggles.
I ride my local state park trails at night a couple of times a month during the warm seasons (this is allowed in Ohio). Good lights used to be really expensive, but now you can outfit yourself with a light and a back-up for around $50. It gives a totally different feel to the trails, and lets you get away from the heat (and crowds).
Get some lights and give it a try!
