The first attempt was stymied by, ahem, us not actually having the key for the car's petrol cap (& barnacle and the key being about 100 miles away at the time); the second attempt was called off due to predicted snow; the third was quarantined off by Img's chicken pox; and the fourth was prevented by Img's "mystery virus" (fever, non-blanching rash, trip to hospital for blood tests, kept in overnight for observation, ugh -- fortunately didn't turn out to be anything alarming). We did use the car to get to the hospital, and were very grateful to have that convenience; but on the way back it started violently overheating & pouring steam out of the bonnet and, on eventual inspection by Mr RAC, was pronounced to have blown its head gasket.
Given that our attempts to use a car at all seem to be fairly comprehensively cursed and our time will be much more limited once we both go back to work, I think we're going to abandon (or rather postpone until further notice) the attempt to come over to Cambridge in the near future; we don't really need to try out the extra bikes (in fact the nice man at the Bristol bike shop says he has another model we could try, & we can get there slightly more easily), and we're hoping to find someone else who's going from Oxford to Cambridge who could deliver the moses basket for us -- one friend says they're almost certainly going to Cambridge in the next couple of months, but if any of the rest of you could volunteer something more definite, I'd be very grateful! (rmc28, if this is all too vague & you'd rather get something definite by some other means, please let me know).
It will be a shame not to come and see you all, but hopefully we'll be able to do a general visit for fun later in the year by train (though it's still difficult to do as a day-trip, & it's hard to stay over anywhere while Img sleeps so badly...).
Separate post coming up later about the State of the Baby!
