Not sure what to give that special someone, but want to keep the budget balanced too? Why not a gift membership to tipurdy.org. At five dollars a month it is a bargain. You can decided whether for a month, quarter or even splurge for a year.
The recipient not only receives a daily email notification of the latest topic, but is entitled to hard to find papers on the Eagle Lake Ice Caves, too. On top of that they can partake in members only tours varying from a summer solstice observance at an ancient solar observatory to a light hearted Halloween Tour. Even if that person on your list is not local, they still receive materials associated with the tours.
Information on subscriptions is found right here. Have a question drop me a line at firstname.lastname@example.org.
