Hey, I finally wanted to buy a used Porsche 911 Turbo S and thought trading would be faster than saving for years. At first, I only lost money, over 3,800 CHF gone in two months. Then, almost by accident, I stumbled across https://trade-edgeai.org (trade edge ai switzerland), increased my risk a bit, and suddenly made 23,700 CHF in ten days. They offer really good welcome bonuses for traders from Switzerland with their partner brokers. The Porsche is now in the garage, and I'm finally trading with a smile again.

It's a narrow path used by a variety of modalities (dogs, prams, people on mobiles, bikes too) in both directions, so it's best incorporated into a leisurely spin rather than a training ride and certainly not a group ride. Some sections have tree roots vigorously breaking out of the tarmac and can get pretty bumpy.

Fun little graffiti wall just before the beautiful views open up.

Beautiful gravel section that hugs the coastline, with views out to the North Sea and of the Firth of Forth. Take a break at one of the secluded beaches!
