    I participated with my club team tjcsc in PatriotCTF 2025, and we got 54th overall!

    Challenge: Where’s Legally Distinct Waldo Three

    Interesting. I assumed it was on campus because the past two have been so far, and this seems similar. I immediately notice a pond/lake, a sidewalk with a bridge, an arena on the left, and a big parking lot past the trees in the middle. This should be a piece of cake! Let’s look around on Google Maps.

    Well this is simply too easy 😭. I see the pond, the arena, parking lot, and a pathway. Let’s note the distinct features from a similar POV:

    Center for the Arts eh? Let’s try that… Oops! Somehow pctf{center_for_the_arts} didn’t work… Interesting. Let’s gather some more information in street view.

    Additional street view context

    Concert Hall? Let’s try that.

    Easy dub! pctf{center_for_the_arts_concert_hall} worked! Unfortunate that I wasted an attempt…
