One dark winter/autumn night few years ago when I was out riding in local woods, I’d just went over a little bridge and up the short climb at the other side when I became aware of a bright light of to the right of the trail 20m into the woods. The light was very bright and big and seemed not to be directional almost like the light was coming from the ground. I was spooked, I could not see any movement around the light, no noise coming from an engine or anything, I tried to rationalise it but without going any closer, moving along the trail to change my point if view but it did not change, it just kept being big and bright I imagined the light to be possibly pulsing slightly but couldn’t be sure. Fek it, I’d had enough and pedaled away both perplexed and a bit jittery.
Anyway after another mile or so with my confidence returning a round a bend and there in front of me at less than 10m and at the side of the trail was the the same phenomena. This time I could see it better and see round about it, no-one or thing else there but a large dish with very bright lights and a kinda mesh funnel, it was of course a moth/insect trap, being use by the local conservation group to survey the nocturnal population. The feeling of relief was immmense.
