It wasn't actually summer, since we went in mid-September, but my husband and I just came back from a fabulous two-week trip to England, Wales, and Scotland. We spent about half the time in London and the rest on a coach tour (that sounds so much classier than a bus tour, doesn't it?). The tour took us to Hampton Court, Stonehenge, Bath, Stow-on-the-Wold, Stratford-On-Avon, Chester, the Lake District, Wales (just barely), Scotland (Gretna, Edinburgh, and Sir Walter Scott's home Abbotsford), York, and Cambridge.
We had a blast! I just hope we didn't do too much damage.
