One thing that's been a pain in travelling back and forth to Durham is needing to carry a spare pair of crutches or sticks. About the only time they get used is if we all go out somewhere - my sister's car isn't big enough to sit all four of us and take my chair, and my brother-in-law is currently driving a two seat coupe, so forget that! In practice it's always been a pair of folding sticks as I've never managed to figure out carrying crutches on the chair and still being able to push - and I don't want to add crutch-carriers. But even when they fold, they;'ve been the largest thing in my bags, and awkward enough that they eat up half the space.
So I was muttering about this as I packed, and then it struck me, just order a pair of crutches and leave them up there. So I did, and Amazon delivered them a couple of days after I arrived, in plenty of time to let us do stuff together over the Easter Bank Holiday. I was pleasantly surprised by the price, and that I managed to find the same pair that I used for years, and which have the most comfortable handgrips of any I tried. In fact I think I paid less for them this time than I did back in the 90s! By my reckoning that's six pairs of crutches or sticks I now own, though half of those are in the back of a cupboard or in the loft as just too uncomfortable to use.
If you're ever in need of a pair of crutches, I definitely recommend these: https://www.amazon.co.uk/gp/product/B006J7FX8C/ref=oh_aui_detailpage_o02_s00?ie=UTF8&psc=1
