(details not for pasting forward... Commuting normally would be 10, but yesterday was Take-Your-Kid-To-Work day, and I have three kids. I can only fit 2 of them on the bike rack. Tonight and tomorrow is a short bike tour. Tomorrow's itinerary is to ride from Pizza Port San Clemente to Pizza Port Ocean Beach, vi Pizza Port Carlsbad and Pizza Port Solana Beach. Since it's more like a tour than a shopping trip with multiple stops, I called that "Recreation: 1"

OP, I think your categorization/counting scheme makes sense, and it seems to be working already)
