One at the beginning of the route, and second at the end – to clip it into the chain. Most of the hard routes have fixed quickdraws, so if you like climbing routes harder than 7b/7c you won’t use many quickdraws.
If you’ll visit Turkey in the autumn, pomegrenades will be widely available. In Geykbayiri camps, they grow everywhere so you have a great source of truly natural fruits for free. Remember to eat only the seeds – the best fruits, are the ones, which are already cracked. You should break it with your hand (using knife is not the best solution) and put out all the precious seeds. And that’s it – ready to eat. Full of vitamins and other goodies 🙂
