Rob,
I didn't think it would be a go-er, but I've just had some work time freed up as of yesterday for the 30th. Train fares are pretty reasonable. Wife has yet to be tackled on the issue, so I've devised a three option proposal for her. She's out with a friend at the moment supping wine, which is a good start.
Option 1 - I come down to London solo, spend lots of cash, doctor the receipts on the way home to prove that I've only spent a couple of quid on these toy soldier thingies.
Option 2 - As option 1, but take my boy down with me. A little more expensive, as he's now old enough to read and understand the price tags, so some form of bribery will be needed.
Option 3 - A family day out to St P. station, at which point we ditch the girls to go and do girl things whilst the boys go toy soldier shopping. This is the most risky and expensive option.
Soooo, pretty much looks like I'll be making it in one manner or another, unless she comes up with Option 4 - "No".
I'll get some more wine in the fridge....
Simon
