The Brussels attack hits a bit close to home for me - I was in Brussels in 2009 and rode their Metro (very wide-open, security-free access back then). Zaventem is their main airport; the low-cost-carriers largely use Charleroi airport which is quite some way west. Also, my original hotel reservation was in a notably Muslim neighbourhood (the reservation was made by my airline; the original hotel was full and I got re-booked to a different hotel closer to the centre).
Still sticking to my travel plans for later this year (Singapore, Riga, London)...not giving in to terrorists or the often ham-fisted domestic (security) reactions to same. Terrorists want to disrupt our lives and make us too fearful to travel or otherwise live our lives, and I'm not giving in to that.
...and still enjoying Stella (the Stella sold here is still brewed in Leuven).
