Jim,
good to hear that most of the physical issues are behind you. Get strong and enjoy your trips. I'd really love to do Machu Pichu. But until I get my knee replacement -- hopefully later this year -- that's not a possibility.

The rest of your travels sound really wonderful with lots of incredible photo ops. Hope to see your posts here. Actually, looking forward to sharing those trips with you vicariously.

Have fun. Savor every moment.

Jim
