I was on my daily walk when a thunder shower surprised me, so I spent over half hour under the tree, but that was a good and dry shelter to be. At the end sun started to shine again and  pointed me where the treasures are. Now I need a boat to get there. Other end of rainbow was in the mainland and I found big amount of chantarelles.

Unfortunately battery of my camera died just when this rainbow appeared and spare battery in my bag was also dead (stupid and sloppy me). So this time I had to use my phone.
