So having earned the badge by getting 13 of the 15 riddles i'm unable to solve the remaining two. The I can't access them as the challenge page has it as completed.

Is there anyway I can get the answer to the two I missed out on solving. I feel like I need closure.

One is referencing where JFK was married, the other the Duomo.

JFK was married in Newport, RI. The Duomo is in Florence, Italy. But I haven't looked at the riddles to see how that information can be used to solve one of the riddles, so that may not be at all useful.

Yeah I'd worked out beyond that, but I couldn't get the answer. Can't say how far I got without giving away clues (or red herrings maybe).

I have the badgelet but can't remember the questions. If you have them, send me a message and I'll see if I can help. No promises, it was all so long ago...

I had a copy of the questions. These must be the ones you are referring to. Unfortunately, I didn't save the answers.

In the capital of Tuscany, the Duomo looms high,
Stand at the entrance, and gaze towards the sky.
Above the door an angel starts your search,
Just put her name with Vatican City's great church.

Start in the city where JFK was wed,
At the place where tennis greats live, it might be said,
Follow that main road south as far as it goes,
To a weird named beach that you'd be hesitant to dip your toes.
Add an -ION to this to get your target quiz,
And literally you'll have found it, you trivia whiz!

I've exchanged PMs with the original poster as I kept all the riddles and the answers. I had to look at them again myself to remember how they worked, though.

Success at last after another round of trying ... but still no idea about number 2 and still no idea why I can't find the right quiz for number 15. Ah well, now on to the sequel! I hope it's OK to say that I needed to look elsewhere besides Google Maps for the JFK one after being frustrated for ages and that there is a (previously-reported but uncorrected) gender issue with the Duomo angel.
