Thanks to all who posted!

I'll be traveling in November - any suggestions for things to see that time of year?

Old Sarum is right there:

If you have an afternoon where the weather is not nice, you might try The Salisbury Museum which is in the Close across from the Cathedral. I did not allow enough time there this Fall, mainly went to see a special Turner Exhibit they had but found their permanent collections to be quite interesting. Here is their website so you can see if this might interest you.

I also enjoyed the walk around Salisbury given by guides from the Tourist Information Center. Looks like they are only doing them on the weekends during November. The most surprising thing was having the guide take us in to the lobby of the Cinema and good grief...there is a Medieval Hall in there! Slightly restored but Medieval nonetheless!
