On 05/05, I will be in Geneva, running the Geneva marathon. Regarding "security" and what just happened at the Boston marathon, I have the following questions/observations:

- My flight from GVA to IAD arrives at 1455; from IAD to ATL leaves at 1740. Will 2h45m be enough time to clear Customs and the TSA at IAD? I have GE (not sure if I'll be able to use PreCheck), but I'm traveling with a non-GE/non-PreCheck US citizen.

- The London marathon is this coming Sunday--if anyone here is in the London area, I'd be interested to hear what sort of "security" is implemented, and if I should look forward to near-martial law in Geneva.

- I had asked before about bringing a bunch of Gu with me. I was told there should be no problem (I'll put them all in a Kippie bag, of course), but I'm wondering if the Boston marathon bombings are going to have the pizza-box brigade on high alert regarding a zipper bag full of little silver gel packets. I'm not concerned about theft (they'd have no use for the stuff); I'm more concerned about missing flights or having to "voluntarily surrender" the Gu to the trash because a pizza-boxer is taking an "abundance of caution".
