We're from Michigan (USA, Detroit area) so cold doesn't scare us, but since we'll be at the end of our long winter also it would be nice if these cities were into "spring" weather at least. Constant cold rain would be a real damper. Spring weather and sunshine would be great.
If the weather was poor, would we lose out on a lot by not being able to see/enjoy/explore the outdoors?
I know it would be better to go in June, but I'm not sure we can fit it in during the next 2 years before our oldest son goes of to college.
