INTRODUCTION
My parents have recently moved to a place near Plymouth, and all they are currently out of the country travelling they will be back for a month or thereabouts from late October. I will be visiting their place in mid-November. I have asked for leave on the 9th and 10th of November so that I can go down on the 8th and come back on the 13th.
THE JOURNEY
To get from King’s Lynn to Plymouth (nearest station to my parents’ new place) by public transport one needs to to travel from King’s Lynn to London King’s Cross, get a Hammersmith & City line train from King’s Cross to Paddington and then travel from Paddington to Plymouth (I already knew this). The journey takes in the region of six hours (I expected this to be the case but until I investigated did not know for certain). This why I requested leave for the two days concerned because the two days on which one travels are not going to be much use for anything else.
THE TICKETS
I discovered via www.thetrainline.com that tickets were available for £57. Thus I have made the booking and picked up the tickets.
COLLECTING THE TICKETS
Having made the booking I was assigned a code I could use to collect the tickets:
I decided that memorising an alphanumeric code of eight characters would be a bit of an ask even for me, so I called in at the library where I could screenshot the email containing the above, paste into paint and edit as appropriate before printing at a cost of 10p.
From there it was a short walk through the park to the station to pick up the tickets.



The email giving me the code to collect my tickets also included itineraries for both journeys.

SUMMER CHALLENGE
I recently received (by email) my certificate for having attempted all 100 of the problems (almost 50,000 people attempted at least one of these problems, of whom 1,797 attempted the whole lot).
Here for you to peruse if you like are all the problems:

A PUZZLE OF MY OWN CREATION
Archaeologist and adventurer Idaho Johnson is near to making the biggest find of her life, but to do so she needs to get past the “Door of Death”:
Can you fill in the missing fourth vertical panel of numbers and get Ms Johnson through the “Door of Death”? As a bonus question can you identify the real door that I have used to create the above image?
PHOTOGRAPHS

Congratulations to the certificate and you puzzle is puzzling. I can see there’s a pattern, but I’m bad at math. You catched a squirrel on camera, that’s not easy, they are never still.
I will reveal the solution to the puzzle some time in the next few days, when I get time to do so some more blogging. You are right about capturing squirrels on camera – it is a challenge.
