Now in Ukraine are very hot, so there is nothing better than relaxing on the beach. I love (for lack of a sea or ocean of course)) to spend time with friends somewhere in the river or lake. Preferably away from the city. Swimming in the lake is an integral part of such a pastime. That's what I want to say, remember the safety on the water. Any water area is fraught with danger, no one is immune from convulsions or dangerous objects on the bottom (and sometimes - dangerous animals). So, swim only in good health and do not swim for the buoys
