Sinai's favorite activity these past few months is riding the steam train in Tilden Park. I take him at least once a week. Grandpa joined us last Friday for three or four rides. Sinai enjoys all aspects of the ride: getting on the train by himself-holding his ticket and waiting for the conductor to take it-repeating "all aboard" when it's called out- going through the tunnel or noo-nah as he calls it-getting off by himself-and finishing the ride off with a sip of water from the fountain.It's such a joy to see Sinai truly enjoy himself.
