A reader wrote to say that Fenway Park in Boston has peanut free seating. If you are interested in the peanut free seating area, you must contact the Red Sox and request to be put on the waiting list. The reader says that those on the waiting list typically receive a phone call when seats are available in Conigliaro's Corner. In the past, tickets have run about $25 each.
This is great information! Thanks so much for sending it. If anyone else has additional information to share about peanut free seating at Fenway or any other ballpark, please email me, email@example.com, and I'll pass on the information about these sought-after tickets.
