It's definitely Spring. There have been some interesting things happening in the gardens of Pittsburgh. Besides seasonal decorations, like shamrocks in March and egg trees in April, some folks go all out with their yards. Or in this case (left), their postage-stamp sized front porch.
This district is made up of row houses, built in the 1880's and originally occupied by mill workers. The houses are generally narrow and have common backyard areas. most have stoops, very few have even a small front porch.
