Okay, I took everyone's advice, and agreed that my DH's idea of celebrating a BIG anniversary by retaking the 21 Day BOE was a good one. The next difference of opinion was when we should go. I was plumping for September, when our actual anniversary falls. But DH suggested the first tour out of the gate, in mid-April. (As some of you know, he's very active in politics, and 2018 is an election year. Most state and local races are up for grabs in 2018. So he doesn't want to be gone in the fall.)
The more I thought about it, the better the earlier date seemed. For one thing, it comes a lot sooner! I was not happy thinking it would be over a year before our next tour. And most of the towns we visit will not yet be sick of tourists.
I've been thinking a lot about retaking tours, and do see some value. For one thing, we know what parts of the 21 Day BOE we weren't crazy about in 2011. So we're already planning ahead, deciding what we will do in those segments of the tour, what changes we will make this time.
So, only 258 days until our tour starts! Woo-hoo!
