Hi Alexey, thank you for liking my Garden Fountain project. Looking at the picture on top of your profile, it is fun how much that looks like the mountains of Northern Arizona, USA. Nice view!
Are you sure? yes | no
Hello, Bharbour! Yes, we have beautiful pine forests and birch groves! But the mountains are also very attractive. Once upon a time I lived in Kamchatka, in a military town, surrounded by volcanoes (Klyuchevskaya Sopka was at a distance of 30 km) - I miss that nature.
Hello Alexey and thank you for the follow/like for #The Cardboard Computer - IO is my name :-)
