Good point about the sunglasses. I've been thinking I need to buy some very light-colored ones, because I especially like having them on in late afternoon/at dusk because of bugs, but mine are too dark.

As for making "eye contact," I will usually turn my head slightly toward the driver and give a nod, maybe a smile. It's easy to tell if they see me because they respond. If they don't, I may wave if I'm really feeling the need to know that they see me. Also, I will hang back and not proceed if I'm unsure. (That's on lightly trafficed neighborhood streets where it's not a big deal to wait; nobody else is held up.)

As a fresh newbie on these boards I learned not to use the curb. Thanks for the great training!
