Driving from UK to Spain, taking the eurotunnel - what's security like at the borders? Hi, I'm going to Barcelona at the end of May in a car with a few friends, we're making it a road trip and taking the channel tunnel. I was just wondering, what kind of security checks will we encounter? Can I just bring my kratom in the bag it arrives in and assume everything will be fine or should I package it a bit more stealthily?
