OK, so I wasn't planning on riding late last night, and I usually ride with the rose lenses in my glasses.

Some of us were riding after work on the levee, planning to go out 10 miles, and back, before it got dark. But one of the guys convinces an office newbie to ride the path too, on her beater bike. So we take off, she quickly falls behind, but we plan to pick her up on the return trip. Which we do, and she's walking her bike. Flatted, no tools, no spare. One of the guys (the one that said "come on, it'll be fun...") gets voluntold to ride hard and fast to go get his car and come get her. So now there's 3 of us walking our bikes back because the sun is setting and we aren't going to leave her alone. Eventually he comes back (stopped by a train, twice), and gets her. So the two of us can finally head in, and in twilight, with the rose lenses, it's plain dark.

Moral - if you're planning to ride late, bring the spare clear lenses. Rose lenses are too dark in low light. And in the dark it's really dark.

Yellow - I do have a pair of them in my car for driving in hazy conditions. Helps sharpen thing. They're popular for shooting, but my riding glasses didn't come with yellow.

I bought my glasses with inter-changeable lenses from Terry - dark grey, rose, and clear. Pretty much stick to the rose. But I may be making a little pouch for the clear ones so I can have them with me. Why is it that when you're crunched for ride time, mechanical *issues* happen?
