Upon opening my mailbox earlier this evening, I found an application from the good folks at Office Nomads for their Park(ing) Day park. This makes it the second year in a row that they have participated in the Central Park; here is a photo of their co-working space from last year.
One of the highlights of their park is that they will provide wi-fi access to anyone who needs internet access during the day. So if you'd like to participate and still have some work to do, their co-working park is the perfect place for you. I would also like to say that I especially welcome their participation because their business is founded on re-envisioning space. While Park(ing) Day is about converting unfriendly outdoor spaces to inviting places, I would say Office Nomads is about doing the same for the office environment: as a reformed high-rise worker, I can vouch for the difference in the two settings.
And not to show all my cards, but emails regarding a park being hosted by a design journal that participated last year have been circulating. Here's the registration form if you'd like to build a park too.
