@Catrin, so to answer question, I haven't gone on anything longer than a 15 mile total, in town, with a stop at Starbucks in the middle rides, so I don't carry water thus far. I'm happy you've told more about the importance of water. I guess I just didn't realize it was important. I drink a ton of water each day (like a gallon), but typically don't while exercising - usually before and after. So I'll take water. It will be in the pannier for now, so I'll have to stop, which is fine, since this is a scenic ride.
@ Darcy, I've ridden my bike from the flatlands of Beaverton up and down the hill to the Oregon Zoo, so I'm comfortable with hills (with the breaks on coming down).
I definitely agree to buy something if I use a cafe's toilet - just common courtesy.
I tried on some Tifosi sunglasses but didn't buy any today. I have just generic sunglasses I could use.

Thanks for all the input.
