Duh!

We spent several days driving in Ireland and found that all roads were well-posted when it came to speed limit signs. Kilometers per hour are displayed as just a sign with a number in the middle surrounded by a red ring. We always joked saying the speed limit must be the maximum speed anyone had ever driven on that road and survived, because we never even came close to the speed limit except on the motorway (freeway). When we started driving in Scotland, we couldn't believe how low the speed limits were! Not all that many people were speeding, but it felt like we were crawling along, and the speeds are not as well posted as they were in Ireland. When we arrived at our B&B that afternoon, we asked our host about the speed limits. It was more than a little embarrassing to be told that the speed limits were miles per hour, not kilometers! No wonder we felt as if we were crawling! Duh!
