Years and years ago, probaby in Sunset mag, I read about growing lettuce in a wheelbarrow. The point is that it can be moved into a shadier area as the day heats up. I have the opposite idea. We live in the mountains where a normal midsummer day gets up to about 75. Also we don't have many sunny areas but we DO have many squirrels and chipmunks. I got to thinking that I could plant lettuce in a wheelbarrow and "chase" the sun around my deck. Anyone have any thoughts on this?
