I work from home on Fridays, so I think tomorrow I'll wait until a little before lunch time so I can investigate some of the possible ways to get down there that aren't too clear on the map. The main reason is that I currently have to walk the last part along a busy, boring street. I might be able to follow a residential street instead, if I can find a way to get over to it. Google Maps thinks it's possible, I couldn't find how in the dark.
I ended up with a pretty bad headache a while after I got here on Tuesday, and a minor one yesterday. I felt this morning like I was close to having one, so I'm drinking lots more water and that seems to help.
Getting up at 4:45 isn't so bad. I don't set an alarm on Fridays, it'll be interesting to say when I wake up tomorrow.
