History
	1.0 19/09/06
	1.1 23/09/06 Live
	1.2 25/09/06 3. Added RideCancelled Yes/No
	1.3 26/09/06 7. added
	1.4 11/10/06 10 to xx added
	1.5 08/10/09 3. Apparent logic error for Past & Future rides. Also needs extra where clause in query
	2.0 06/07/10 New feature: Trophy Table navigation support for linkage to ASP.NET Trophy League Results, etc.
	2.1 13/07/10 CN92 16. Revised page name schema for Trophy Table for past results (dropping the p suffix for previous year's), etc.
	2.2 20/07/10 WBR121 3. Filter conditions for future rides was wrong - was selecting closing dates in the future
	2.3 02/12/10
		4. Dev. Next Year Schedule from dB - need to handle both scheduleX.asp & nextyearscheduleX.asp where X is d or a
		1. Dev. Add RideType: PQ (Perfeq)
