rainforest is info in rarest.

[geo0939]

Sorry mallam, not rarest but rare (unusual) ST= street (way). Info is dope as you say.

Im sure you're right, geo. I jumped to a conclusion there. It wasn't 'most unusual', but 'rarest' can mean 'very unusual', and I seem to remember I thought it was a new wheeze for coding insertion: "in the way of 'unusual'". Not even that new, but 'st' for 'way' is such old hat. Setters are scraping the barrel these days, and I feel sure Ive seen sth like that before.
