There are many blueberries in our house and we are always taught to be careful about picking them as beer :) So yeah, you're lucky that you do not face any bear. They feel bigger and fat at slow speed, but you can say that they do everything - down the hill and down, climb a tree, swimming and everything they are better than us.
You've taken some great photos and I'd like to share some photography tips. Thanks for that!
