Mrs. BD reports today, after trying Gibbs' recommendation, that a paste of vinegar and baking soda is quite effective for poison ivy. (Remember McGeek's case of poison ivy?)
Mrs. BD is highly sensitive to poison ivy, but when she gets weeding she stops paying attention and just rips along like a weeding machine.
Gibbs is usually right about things. I made her take some Benadryl too. Partly to compete with Gibbs, I guess.
