The past several weekends I've done litter pick-ups on my street (39th just south of Rainier) and I'm interested in coordinating efforts with others in the neighborhood. I like early mornings on Saturdays and/or Sunday before the day gets busy and it's a beautiful time for a walk (like 6am to 7am! on the way to the bakery - but negotiable). I know Cleanscapes does litter pick-up most days of the week on Rainier but I don't think they do side streets and I don't think they pick-up litter just slightly onto private property.
Even if we don't do the litter pick-up together I'd like to coordinate efforts and learn more about my new neighborhood - it's great.
