In other words, it's not just a museum and an art gallery, but also a still-in-use government building that the public and tourists have the pleasure of being able to visit. It was one of the absolute highlights of my time in Boston.
So why – just as I was putting my metal belt back on having passed through security – did I get that brief shot of panic at the offering of a guided tour?
I love history and I love architecture and more than that, I love taking photos, so you'd think a tour of a building like this would be right up my alley. And maybe it would. But more often than not, I like to do things in my own time. Sometimes I can race through an attraction – even a museum I really like – in half an hour. Maybe even 20 minutes*.
It's not that tours can't be great, it's just that you're only fractionally less likely to win Lotto than you are to land on a tour that goes at the pace you want. I've been on city walking tours where the "walking" needed inverted commas. A three-hour "walking" tour where you stand in cold and wind for 20 minutes at each notable spot before moving several metres to the next one is not exactly how I want to spend my holiday time.
And yet the same tour done in half an hour? Sign me up!
*For the record, I was in and out of the Massachusetts State House in 34 minutes.
Asking for "Wah-der" in the USA
Staying with America, I have a little secret. Every time I'm there and I'm ordering water, I put on an American accent for that word alone: "wah-der". It's just easier than having to explain what to American ears sounds like "war-dah". Request a "war-dah" and you get blank looks, but ask for a "wah-der" and you're away laughing.
The only issue is – and this is where this becomes a travel bug for me – is when you're travelling in the States with other Kiwis. I was recently with three Kiwi friends and the sniggers of laughter you get from your fellow countrymen when you're at an American restaurant asking for "wah-der" are enough to put you off your "wah-der" and just get a Coke.
