Trade in your advice for future (or current) Cincinnatians in exchange for a hot, soft sourdough pretzel created by Christian Schmit. A roving pretzel advice exchange cart, this rolling art piece's exact location may be hard to pin down, but it will be in the Findlay Market area of Over The Rhine Friday and Saturday afternoons until the pretzels run out. Follow your nose! Part of the Advice for Future Homecomers project at People's Liberty.
