The golden Autumn is not far and you can make a little walk in the forest and find some early mushrooms even today.
You should not forget to take with you your little pocketknife and little bucket to pick some mushrooms.
You can make some cool photos or just pick mushrooms and make a good tasty mushroom sauce - the choice is yours :)
One more thing! While in the forest take extra care not to lose your cellphone - just in case you should need one ;)
