We live next door to a family with 3 boys(dont know exact ages but I would say maybe 5,8,11 years old). They are well behaved and cause us no issues at all during the year except for this issue. Every time we have any appreciable snow they come into my front yard to wrestle/play fight/throw snowballs etc...By the time they are done my front yard is a muddy,snowy eyesore. I know in 2-3 days it will all be melted anyway so what's the point in making a big stink about it. However somehow the way the sun hits our yard its always the last house on the street for the snow to melt so it ends up looking like an eyesore longer... Do you let it slide or do you say something to the parents?
