Yup, SkyVenture New Hampshire is real, it is being built in Nashua, NH, and it should be open to the public in early August. As with any construction project, unexpected things can happen, and those unexpected things rarely speed up the process. But, I think the early August date is looking pretty good... So, I would check out [url http://www.skyventurenh.com]their website[/url], and contact them with any questions/concerns that you have (or PM me, and I'll offer you my opinion). Also, the owners have also posted a bunch to [url http://www.dropzone.com/cgi-bin/forum/gforum.cgi?post=1841794]this thread[/url].
As far as being concerned about being one of the first to fly in a new tunnel - not to worry - the systems will be well checked out prior to allowing the general public to fly. They have to train their staff somewhere
Why would you go to Eloy or Florida when one of the best tunnels around is in your back yard?? Unless you just can't wait another 3 weeks or so to fly Hope to see you in Nashua soon.
