Honestly, I don't carry an umbrella or a poncho. I think umbrella's are too much, and if the parks are crowded, you could hit somebody in the head. Poncho's I guess could be a better choice, if you are concerned about your hair or something .. If it rains when I have my hair down, then I'll put a poncho on. Usually (especially in the summer months) I wear my hair up with a hat, and just get wet.. You'll dry off eventually. Or run for cover, go eat lunch/dinner, watch a show, etc...
