Of course he could...
But in the event of a no-deal which he appears to favour, it will be reliant on:
If he pays for an online visa (ETIAS), as will shortly be required for 'third countries'...
Makes sure he has adequate private health insurance (currently covered for free by EHIC)...
And of course if he can afford to do so given our crashed currency...
Heaven forbid that he would maybe like to take a car to the continent with all that would entail...
Or fund his journey by the odd spot of work whilst over there (which many of us have taken advantage of)...
But luckily the duty free limit will be re-imposed, thus he'll be able to carry his entire allowance on his brexit bike!
But hey ho - that's what quitters voted for
