Garfield, This must be confusing so I hope this helps clear things up
BAC is in Gillette (Foxboro) on ?
DC show in Bristol on the 3rd? Parades on the 4th
BSO is in Tanglewood (Lenox) for only the 3rd
Boston Pops rehearsal is at the Esplanade (Boston) on the 3rd
Boston Pops performance is at the Esplanade on the 4th (full Pops orchestra with Keight Lockhart)
BAC & BD with the Pops at Tanglewood on the 6th
If you want to see BAC at Gillette, the BSO, Bristol, Esplanade events, then Tanglewood again, you'll be doing a lot of running around. But if your wife wants to see the BSo, you have one shot at it.
