Puzzle has been updated to account for the 2021 redesign of the transit system (and changes thereafter)! If you have an old solution kicking around, it will still work.
I left my house last Monday and decided to take a trip around the city.
- I got on a bus going south at 109th street and 68th Ave, and got off at the first transit centre I came to.
- Having no particular goal in mind, I decided to get on the first palindrome-numbered bus I saw that wasn't going back the way I had come.
- I had to get off at the next major transit centre, as it was the end of the line.
- I missed the bus going to West Edmonton Mall. Instead, I got on an east-bound bus of the same line, which took me past Calgary Trail.
- At the end of the line I thought it would be fun to take an express bus north.
- When I got downtown, I walked to bus stop #1064 and took the highest single-digit bus number listed on the sign.
- I got off it immediately after crossing the river.
By this point, I'd had about enough, so I continued on foot to coordinates N 53° 31.abc and W 113 31.xyz, where I left a cache to commemorate my trip.
a = the last digit of the second bus I took
b = The second digit of a bus stop number at the second transit centre I reached.
c = The sum of the digits in the number of the third bus, minus the sum of the first two digits in the bus stop where I got off said bus, minus 1
x = the last digit in the bus stop where I got on the express bus minus the first digit of the express bus route, divided by 2
y = the sum of the first and last digits in the last bus stop number where I ended my trip
z = the number of the only route I took twice.
Please send me a message if you think there have been any route changes that might affect my repeating this trip. If you'd like to find my cache, you can retrace my steps, or ask your computer or transit app from the comfort of your armchair.
