The son of President Arthur, Alan and his wife purchased the house, remodeling and expanding it to accommodate their extensive calendar of dinners and parties. Alan became deeply involved in the social life of the Pikes Peak region and Edgeplain became one of the outstanding meeting places of the social leaders from Colorado Springs and Denver.
