As Jughead wrote, commuting to reserve sucks but if you live in your domicile, sitting a M-Th reserve line was better than holding a Th-M hard line IMHO...at some airlines, if you are senior and bid reserve (especially at an airline with a lot of new hire training going on), you can be home (at least) 27 days a month...man, those were good days!
I commuted to my guard job and found that easier than commuting to my airline gig but that was all pre 9/11, things have def. changed since then...
