If it is too cold to go outside go bowing. A place to go is Bowlero. Just so you know a lot of times they have loud music, Bowlero so if you have a young one have someone take care of it at home.
All kids love it they not only have bowling, but they also have a small arcade. In my opinion the bowling is better than the arcade. The lightest bowling ball that they have weighs 6lb, but you have to go up to the desk to get a six pound bowling ball. I would say it is for ages 7 and up, but your little ones could tyy bowling to, just to have some fun. If you want guard rails you have to go ask the front desk to put them up on your lane.
