Thanks for the advice on mint and aloe, guys. I was talking with my ex, Julie, and I was asking her if there was such a thing as Frontline for humans, and she said, "it's called bug repellant". So I'm going to try some aloe and/or mint to see what I can repel. My cats will probably want to lick me if I have mint on, though, so I'm not sure that's better (other than the lack of fear of Lyme disease -- which is a big plus), so will probably try the aloe first.
PS I love trains. I think it's really cool that you can go to completely different countries in Europe by trains, and have always wanted to do so.
