No show??

I'm considering being a "no show" for the GO half marathon next Sunday, and doing the Blodslitet instead. It's all becoming too hard. Pros and cons:

GO Marathon	Orienteering
I'd have to skip Street-O on Saturday	I can do the Saturday Street/Park event at Lilydale Lake - a new map, and an area that used to be one of my regular haunts
I'd have to drive 3 hours to Apollo Bay on Saturday afternoon, leaving enough time to find accommodation	I can get a lift to the Blodslitet with Pete and Ilse
I'd have to get up waaaay too early on Sunday in order to catch the 6am bus to Kennett River	I'd still have to get up far too early, but I could probably stay in bed until 6am.
I'm not going to know anyone, unless some CRs make themselves known	I'd know 80% of the people there
I've already paid $60 and got the t-shirt	It'll cost me $10 (wahoo)
It'll cost me a lot more than that for food and accommodation
I've never done a 1/2 marathon before	I've never *completed* a Blodslitet before (I DNF'd last year)
