I'd like to suprise my husband this next february with a trip to one of Oklahoma's state parks. Can anyone suggest something for that time of year.

Quiet Family type would be Greenleaf State Park http://www.shopoklahoma.com/greenlea.htm
Beavers Bend has about anything you would want to do http://www.shopoklahoma.com/beaversb.htm
Western Hills at Sequoyah State Park http://www.shopoklahoma.com/westernh.htm
and don't forget Robbers Cave at http://www.shopoklahoma.com/robbersc.htm. In the western part of the state you have Quartz Mountain and Roman Nose. Have fun.
