craftgrrl | should i knit my scarf longer?

hello grrls.
im making this scarf you see... and im from canada. im living in texas now and i think scarf style is different (for one... you only wear scarves for 3 days during the winter!!)... but i think in canada we wear scarves that are a lot longer, cause we wrap them around our faces AND necks (its chilly) but im wondering if i should keep my scarf this length, or make it longer. does it look silly this short? or is that pretty normal for a scarf and im just canadian?
secondly... im just reaching the end of my ball of yarn, i have two more, but id really like to make another scarf. possibly three if this is a good length.. so i hope this is long enough and i can make 3 scarves this length instead of two... make sense? ANYWAYS, any input would be greatly appreciated : )
