This is something that I should imagine we would all love to do is get out of the 'rat race' but the problem is having the guts to just give up everything, the problem is the trappings of life, house, mortgage or renting? car you name it, its all there and for some not all find it hard to give up all those things! personally I would find it hard to just pack it all in and sell everything and live in a caravan.....but in saying that there are a couple of members in my family that have done the very same thing just drifting around the country and we never know where they are from one week to the next! but if they are happy in what they are doing then I say go for it!! I wish them all the very best for the future.
