Scuba divers! (New York)
So, i've been diving routinely back in Singapore. However, coming to NYC and in this freezing weather - scuba really isn't what would be on top of your 'things to do in NYC' list.
I have discovered this place called DutchSprings. It's a scuba amusement park (wow! don't have that back in S'pore or neighboring countries). It's great for seasoned divers (up to Protected content and they offer lessons to qualify new divers too.
Although we are allowed to dive alone - i much prefer going with buddies. Even if you wish to get certified, i'm happy to tag along. Just needa get some bubbles back in my life! who's interested?
