The Bank of America Chicago Marathon, this Sunday, will box me in unless I have the foresight to park outside the race course before then. I'm not sure what to do about Parker, either; there are a couple of underpasses from where I live to the park, but it looks like from the time we wake up until about noon Sunday we're not going to go very far.
The weather should be really good, though possibly a little warm. Good luck, runners!
