At a park we like to go to, they have a greenhouse and they decorate it with lights. We went this year and it was pretty cool. Next year we need to not go on the last day in the last 2 hours that it was open because it was pretty busy. We had fun and I brought a thermos of hot chocolate that came in handy when we had to wait outside for a few minutes before we went in. Lucas liked touching the plants and the lights.
