I should never discount the therapeutic and logorrheic value of a park. I got immense amounts of work done on my Rabbinical School essays at Holmby Park. I took my dog on a walk (though he'd like to think that he's taking me on the walk). After a while I sat on a bench, extended his leash, and took out about 18 pages out of my pocket. As Tuggy tried to chase squirrels up a tree, I made a lot of progress.
