WHY is there NO Public Transpostation in a LOT of Area on Weekends & Holidays?I dont Drive To Save the EARTH?

I Am an ECOLOGIST that means that I am VERY Serious about doing all I can to HELP SAVE THIS PLANET...I Have NOT Driven a Vehicle for NINETEEN YEARS,Because I feel that the Sacrifice is worth the Gain !!! If More People Used Public Transportation We WOULD Have Less Polution !!! But there is a Greater Sacrifice Because I CAN NOT GO VERY FAR ON WEEKENDS !!! I Live Out of the City But on Routes that HAVE BUSES & TRAINS !!! In EUROPE the Public Transportation is MUCH BETTER....I Don't Like to Bad-Mouth the Industry,But Can't The Government Subsidize These Days so the Public can get to Holiday & Weekend Activities ??? It is not so bad on me Because I am Retired,But People Working on these Days Must Have a Tough Time---PLEASE, You in City & Government Positions Research This Issue & Seriously Attempt to Solve it For ALL Involved---Signed---JEM
