There is some yardage from rps quote above, I've always considered the GBBF an expensive day out, taking in the travel, entrance fee and cost of beer, bearing in mind I rarely drink more than six pints a visit, usually in halves. However I go there to find and taste new beers , all under one roof, I would be spending a lot more traipsing all over the country, however enjoyable that may be, finding these beers. I personally can't afford to do that too often.
