Yesterday I was on western Slovakia, near Mikulášov and Studienka.
Its very interesting area with biggest sand dunes in Slovakia (...thanks to offten Slovak army tanks trainings...).
There are lives a many sabulophiles, - sandy locality is much more warmer then other surroundings, with special botany and insects...
I made some pics for U:
