I can pur TT at work a few ways
1, a lift by someone unknown to us, a friend, co worker etc - very unlikely as I think we would have heard about this by now.
2, DA dropped him off - possible if she was still awake from the night before but otherwise unlikely since she by her own accounts was either up late playing games at home or working late at a club
3, RT dropped him off before returning home to get ready to meet friends - possible but not one I'm sold on as although it would work when school was out, it wouldn't really be practical during school terms.
4, CA dropped him off as claimed - again possible but, even without cancer complications, its not really a sensible option to me for CA to be going out of his way to collect TT when bith his daughters with cars were living with TT.
5, FA dropped both him and CA off - possible, but same issues as number 4
6 TT drove himself to work in his own car. I am far from convinced that the olds mobile (OM)was the only vehicle they shared. The OM is always referred to as RT's car. In no newspaper accounts does it ever say she was driving her husbands car that day, which in the 1970's it likely would havebeen mentioned that way imo. TM recounts a day just after RT married where she called to see RW and show off HER new car - the OM. The keys TT took to SS are always referred to as 'the spare keys', not his set of keys but the spare set. TT had to get to and from work everyday, and although he claims it was usual for CA to drive him, it doesn't feel like it makes sense for that to be the case, and couldn't have been the case during periods where CA was in Dallas receiving treatment. Plus I feel like it would be normal for a husband to check with his wife if she would be home from shopping in time to take him to bowling if hers was the only transport they had.
So although I know this logic is far from conclusive, its all I have nearly 50 years on, so going off this I am as yet unconvinced that TT did not have another form of transport he could use, be that a car or truck belonging to the shop.
