In Canada we have a higher "compliance" of breastfeeding than in the US. The average Canadian mother breastfeeds longer than her US counterpart. I think, as a result, breastfeeding in public is possibly more accepted, although I'm sure there are still a few people who get their shorts in a knot over this...although I've never seen it personally.
When my son was born last year, I woud definitely breastfeed in cars, restaurants, parks, but was discreet as I could be. i.e. I'd try not to expose my breasts, but had t-shirts that had a flap, or covered up with a baby blanket. It wasn't a big deal.
It shouldn't be a problem.
