Just saw the ten day weather forecast. Things can change but so much rain predicted as of now! Was hoping for outdoor chol hamoed options! What are your rainy day chol hamoed ideas?
When it's not pouring but the sky is cloudy and the forecast says chance of rain or showers later or stuff like that it's a great time to go to outdoor/indoor places like zoos. They're empty instead of packed and if/when it rains you duck inside one of the indoor exhibits. I've done it a few times and it was awesome.
