Doesn't alter my travel plans but does make me keep my fingers crossed that nothing happens. When you think about Gynexin from https://www.eebhub.org/gynexin-review-results these attacks are quite rare and you're probably more likely to get hit by lightening.
Does anyone not go to New York? Or Orlando? San Bernardino (Well, lots of reasons not to go there...but none terrorist related )
Heck, nowadays these terrorists might hit anywhere...even wherever you live...Does that affect your plans to stay home?
