Can you walk and sketch at the same time?

Mari Le Glatin Keis has written and painted a wonderful book for those of us who would like to learn to travel and sketch. I made my first attempt last August while on an Alaskan cruise and got all of two pages completed, both before we even boarded the ship! I understand now that I was doing just about everything wrong and setting myself up for failure. So I was delighted to read this book and study the examples Mari provides from her own work and that of her workshop participants. I don't expect to be traveling for several months, but when I do I hope to have some practice from following her ideas right here in my own community, something to looking forward to throughout 2008.
