This is uncanny. Only today, I looked up at the skies over Lincoln and watched angrily, as they blitzed us with chemicals and I saw a small rainbow. I wondered then if it was chemically induced. You have just confirmed that this is the case. I see them spraying literally every day, but it was the first time I had seen a rainbow when there wasn't supposed to be one!
Its getting worse with all the modification these days.. rainbows are light refracting, can refract off any reflective/clear material.. all my weather shots are chemcally modified weather, theres little real weather theses days.. have you looked at strange weather on youtube at all? also iv got a vid up myself on the subject.. and one ufo vid.. bizkit66effect, if you get chance, im guessing you wont have much time on here
