I never tire of waterfalls. if I were to create a hike it would probably have waterfalls and I'd ask for like, 10 waterfalls, and I'd like it to be pretty flat, only a few miles long. The trail needs to be well maintained. I don't want a lot of crowds either, but it does need to be close to the city. The drive out needs to be beautiful as well. And since you asked I wouldn't mind a nice old WPA lodge - like a mini Timberline with cool furniture and and snack bar. The fire need to be going whenever it's cold so I can dry off. All this should be free - maybe $3 parking or something. That'd be cool.
