An Auntie recently lost electricity due to heavy storms on NorthEast USA. Lot of food was spoiled and she had difficulty going out to buy more groceries. And let's not forget COVID! Plus her Husband is recovering from surgery (still waiting for test results). She lives in the suburbs with single-family home and is looking for generator. The type that attaches to house gas line like an outdoor grill. What should she look for when purchasing such a grill. Can you recommend any?
