Like M14P, any highlights; super high-pressure day, cr*p drizzly and windy, cloudchasing, taking J Bloggs on his/her first flight/first aeros etc. Aeros manouveres e.g B/R, A/R, ST, L (Barre l& aileron rolls, stall turn, loop). Otherwise, runway in use, landing a greaser or teeth-rattler - anything that gives the entry something to remember it by.
Good to look back on years later.
