US 1 and I-93


Ideas for next seasons?

• Two of the same type on a sign where the number is not a route (e.g. gas station prices, parking by number of hours, distance sign, weight limit by number of axles, toll cost by number of axles, bus stop sign for more than one bus)
• A distance sign and a route marker that can get you there OR a mile marker and the route it corresponds to
• Any two routes that overlap at a 90° concurrency or a 180° wrong-way concurrency
• Two routes that do not touch anywhere along the route, but the shields are visible in the same photo
• Any two routes, but the photo must have been taken within the last 7 days
• Any two routes, but at least one must be a terminus

For those who have complained about it being too US-specific, none of the suggestions above are limited to the US.
