Dear Bob.
Our country is not as it is usually described. In the spring we have enough warmth, and April is considered to be the month of flowering and dripping. Our city is located on the river so you should take a jacket and scarf, as there are cold winds blowing in our direction, and it is also worth to grab an umbrella, because at this time we can have rain and St. Petersburg is considered the sa th foggy city.
The streets of stray animals we do not go as we have a large short and considered the Northern capital of our country, so you should not fear.
