I did standing room a few weeks ago at History Boys. The ledge was a bit high, so it wasn't the most comfortable SRO experience I've ever had (not that they're ever particularly "comfy" experiences). I liked the Plymouth (or whatever the hell that theater is now). Their ledge was low enough that you could lean on it, but the Broadhurst kind of came to my nose! Though, I did luck out getting seats for Act II (a pair of people just never showed up two rows in front of us). It is a long show to stand for (great as it is).
Oh, and I guess they're selling the tix in advance ...not sure how far (I bought mine for a Saturday mat the afternoon before the show). I have no idea how many spots there are either.
But when did New Hampshire become--Such a backward wasteland of seatbelt hating crazies?...I mean, only 40 people actually live there. The others are just visitors who come for the tax-free liquor and three inches of novelty coastline. John Hodgeman on The Daily Show (1-30-07)
