The Welcome Center is big, clean and inviting. It contains a large dining area, excellent coffee (from Georgio's, a local roaster), decent counter-food and a wide assortment of local food products. On weekends, there's an outdoor farmer's market with multiple vendors selling pies, fruit and flavored pickles. There are areas for kids to play and pets to walk.
Inside, there are interactive exhibits and a photo area which had a line of eager visitors today. The Center contains an official DMV kiosk where you can renew your license, etc. and a NYS kiosk where you can get fishing and recreational licenses. And yes, the bathrooms are excellent.
If you need to pee, this is the place to go. It was well-attended today by curious visitors, all of whom were smiling. Here are some pics.
