I found it all very confusing as to where I needed to finish. So many colours on the walls, I was expecting things like the YouTube videos I'd seen where there was only a couple of colours on the walls.
Be thankful you're not at one of the weird north american gyms where the holds are all different colours but with different strips of paper attached to em, they're a nightmare. Just take a second before you start to read the route and try and remember where it goes.
What's the etiquette regarding shoes? Someone was just covering the front desk when I went so gave us shoes for free. My daughter found it better to just wear socks though. No one said anything but didn't know if that's frowned upon?
Socks probably ok, although anything but the most easy routes will be tough. No barefoot though, that's gross and you'll get told off

Every weekend recently has been too wet for trad or bouldering and not cold enough for winter climbing! Scotland is looking a bit more promising at the moment though so hopefully I can at least get some winter routes done this season.
