So I did a quick search on this and nothing came up. Has anyone noticed the declining quality of air when out riding? I've only been riding for close to 4 years now but over the past year or so there has been a noticable increase in crap in the air. I might be a little more sensistive because I have mild hay fever, but the short 15km trip to work will sometimes see me turn up with a build up of black gunk in the corner of my eyes. I can actually feel the particulates hit my eyes. Anyone else notice this? Is it due to poorer petrol quality? More cars? Lack of rain to clear dust? I think I might have to invest in some goggles as it's summer and I much prefer visor up!
