Flying around today

Today, I took Manzi out for some flight training. He hasn't been allowed to play in the trees for a few days so instead of flying to me, he went straight for the nearest tree. After two hours he tried to fly to me and missed. It was right outside my apartment, so I just went out to check on him every 20-30 minutes. The rest of the time I left my window open so I could hear him while I was working. After a while he flew down to me to get some treats. He was happy to do a few extra recalls from his favorite tree too. Now he is happily eating inside. I'm not sure if this is a good approach or if I should find a big field without trees to let him practice flying. Today I talked with Chris Biros, the free flight expert, and he gave me some very good ideas. Well, hopefully Manzi won't be such a terror the rest of the night. He has been pretty bad these past few days, probably because he is in a bad mood since he's not been allowed to play in his tree.
