Yeah, we don't freeze scores, so it is definately to your advantage to play in some bad weather and post some big numbers, so you're ready for tournament time in the spring.
Where do you play? Appears as though you are implying you are in a Northern clime, therefore, a place where an inactive season is in effect. If so, your Members are wrong. Posting winter handicaps when in an 'inactive season' is wrong. (Please see Section 6-2 re: an authorized golf association converting you rareas can declare an inactive season even though your Club is not a member of that association.)
Your comment concerning posting 'big numbers' 'so you're ready for tournamnet time' flies in the face of everything golf is. Any one who does this is a sandbagger.. I'll refrain from using a stronger word.
See USGA Handicap System Manual, Section 6-2:
6-2. Inactive Season
The authorized golf association having jurisdiction in an area is responsible for declaring the duration of any inactive season. A golf club located within the area covered by an authorized golf association must observe any inactive season established by the golf association, even if the club is not a member of the association. (See Decision 6-2/1.)
Scores made at any golf course observing an inactive season are not acceptable for handicap purposes. Scores made at a golf course in an area observing an active season must be posted for handicap purposes, even if the golf club from which the player receives a Handicap Index is observing an inactive season. The club's Handicap Committee must make it possible for a player to post these away scores prior to the next Handicap Index revision. If possible, the club must re-compute the player's Handicap Index at that start of the active season.
Example: If a player belonging to a golf club in Michigan plays golf in Florida during January, any scores made in Florida are acceptable and must be returned to the player's Michigan golf club. If the player is also a member of a golf club in Florida, scores must be posted to the player's Florida club.
See also Section 8-3b:
b. Scores Made in Inactive Season
Scores made in an area when the authorized golf association has declared an inactive season must not be accepted for handicap purposes (e.g., score made in the New York City area in December). However, scores made in an area having an active season (e.g., scores made in Florida in December) must be posted at the player's golf club at the start of the active season or as soon as practical. All scores from the active season areas must be posted or if there are more than 20, the last 20 plus any eligible tournament score must be posted. If possible, the club's Handicap Committee must re-compute the player's Handicap Index at the start of the active season.

6-2/1. Establishing an Active and an Inactive Season in the Same Area
Q: In the southern part of a state, golf is a 12-month sport, but this is not true in the northern part of the state. What may the authorized golf association do with respect to establishing an inactive season?
A: The golf association may declare an inactive season for the northern part of the state, but not for the southern part.
