Mirin got a real bow and anrrows for his birthday this year. 

 He's been so excited about it.  Ethan used to teach archery as a summer camp counselor before we got married, so he's been teaching him.  Out at the Farm, Mirin sets up a firing line and a wild watermelon (we call them Notermelons, because they are not watermelons--they are bland like cucumbers and very seedy--we feed them to the animals).  He's actually a pretty good shot (better than I am).  He's very careful about how the arrows are handled and about finding them all when he's done.  Luckily he only has six and they are brightly colored, because the grass is at it's longest right now.

Strangely, having a real bow has set off an even more obsessive phase of making bows and arrows out of sticks and all kinds of things.  I don't have a picture of it, but two days ago he found a hacksaw and cut and trimmed a long piece of oakleaf hydrangea and made a long bow that shoots shockingly well for being strung with cotton twine.  He also fashioned arrows out of palm fronds.  He also had a little crossbow he made with a rocket balloon.
