Summer Fun at the Serpentine

The reason we chose this weekend for our London trip was to meet up briefly with Son#1 and our new Daughter-in-Law (they were married in May, see here). They were passing through London on their way from their home in Detroit to a conference in Stockholm, and we had the chance to have lunch and spend the afternoon with them.
 
The weather was so nice that after lunch we had a leisurely stroll through Hyde Park. It provided today's best blippertunity.
