Usually we take a stroller with because we have so much stuff but this time I was thinking of buying a wagon and using that instead. I'm looking at these:

LO is 3 and it will be pretty cold.

Wagon all the way. Unless LO is a runner. But, a wagon is so much easier. You can put loads of stuff in there, including a blanket. Plus, it's easier to get LO out to see things and plop him right back in.
