While not exactly accurate, just visit Nikolaevsk-na-Amure during the chilly spring months - winter temperatures in Nikolaevsk-na-Amure remain in the cold zone for nearly half the year.
Here was not getting any reception on my mobile phone.
I was scheduled to go to Sakhalin across the Strait. However, there was a big problem. This was due to the Amur floating ice. It has been a long cold winter this year.
The bridge connects the Mainland and Sakhalin Island is necessarily required.
