Furthur tix just went on sale for the tower shows (5 of them!) for Fri March 18, Sat 19, Sun 20, Tue 22 & Wed 23. There was a presale online last week but those were sold out before you could even get online. I sent in to the mail order for the first 3 shows and even had the envelopes postmarked on the first day (1/7). Even with that, when I called GDTS Too about the tix, they said that they had so many requests that in most likelihood my orders would be returned unfilled.
So, as much as I hated to, I logged onto Livenation (ticketmaster) at 10AM today and was able to get decent seats for 4 of the 5 shows. Tix are still avail but gone for Friday, and going fast for the other nites. If I get lucky enough to get some tix back from the mail order I'll let people know here.
PS: There are also 8 shows in NYC, 5 at the Best Buy Theatre and 3 at Radio City so a newbie can get his/her fill of being a tour rat by catching a handful of shows!
