If, per chance, you belonged to the LTA Society out of Akron (the oldest LTA club around) you would get the latest and greatest information on 'NT'. There latest Bulletin has info on this. Also, if you had the list of WEB sites I offered a while back, you could probably find out all you want to know on one of them. Meanwhile keep going back to
www.zeppelin-nt.org/ for updates. Ford Ross, Member ALL the LTA Organizations including the best, NAA and LTA
