I guess this is sort of fishing related, but I was wondering if anyone out there has any experience and suggestions for a good backpack that I can carry my toddler son in while flyfishing? I bought a pretty heavy-duty one at a consignment shop, but it is pretty large and cumbersome. My wife has an Ergo which would probably work pretty well if I could figure out how to get my son in it on my back. Any suggestions would be appreciated. I am not planning on taking him out until this summer so there is plenty of time to do some research. Oh and my son just turned one last weekend so he would be about 16 - 18 months or so by summer. Thanks.
