It does not seem to be much of one at all. We were there about 10-12 times a year for 8 years with a stroller and never had a thing taken even once.
We never have (and probably never will) travel with the BOB. Yes, it is a marvelous stroller, but I would fear for it getting stolen. But more than this, that thing is huge. Using anything other than an umbrella (or slightly larger) would be problematic, I would think. I have seen some links on these boards for some strollers that I think are better than your standard $10 umbrella stroller, but not as pricey or bulky as a BOB.
I will say this... our son spent way more time in it than we thought right through our September 2011 trip (he was 5 1/2 years old). He would get completely worn out and it was the only option. We did use an umbrella though because of the bulk.
Also, if you are going to take it to the gate at the airport, it has to fit through the security screening machine (the one through which all the carry-on luggage goes ). Our first trip, we took the "fake" BOB (smaller and cheaper running stroller that we were not so worried about being damaged or lost), and it was an ordeal with the security. My husband had to take the wheels off and all that b/c TSA insisted it had to go through the machine. And even then it barely fit. After that, it was only smaller and lightweight for us! When you are already wrestling with a child, a ton of bags, a computer, and your shoes (and at that time, milk for the baby), having to disassemble the stroller was not another headache we needed.Thanks for the advice, that's probably what I am going to take. As much as I love the BOB, going down Main St. with it would be like driving a tank down a freeway.
