Well I finally made it, 5 hours of sheer hell. Heavy rain = Heavy spray + the police closed the M4 between J15 and 14 for some reason,Police incident!.
The division that the police advised ,was a nightmare,we were moving mere yards at a time,and we were the ones that were actually moving,those who were stuck on the motorway when the police shut it,were the the ones that were stuffed,from 7.30 to13.30 they were left to fend for themselves.
We were lucky that the motorway was reopened by the time that we had to return, same shitty weather thro.
Ummm.....Let me guess....Off at 15....then to Marlborough.....then Hungerford?

Should have asked a Taxi Driver

I went to Marlborough and back during the 'diversion'.....25 mins each way, using the country lanes:y (tho good job I had a group of young lads on board, as I doubt passengers more mature would have appreciated me doing 60-70mph on the straights

) (usually can do it in 20mins each way using the main roads with a clear run)
Altho if id been heading towards jn14, id have gone Liddington, then Aldbourne.....lovely fast country lanes (easy to keep up 60-70mph most of the way

)
