You obviously did not try to leave at 1715 to eventually arrive in Lincoln at 1900.
Well yes I did actually. Exited the eastern gate onto the A15 at 17:15(ish) with no problems at all, me and three other cars. Depends on your exit point I guess. By 19:00 was passing Nottingham (that A46 going past Syerston gets worse and worse).
Thanks for the info on the Typhoon jockeys though. Didn't think its display was "uninspiring" at all, in fact I thought it was extremely agile (as I said), just would have liked to see more of it. Good "Lightning" emulation on its take off run, pity it was so cloudy on the Sat.
