You don't say where you are. Could you do that? Reason is that there are places where people gather that might provide you with good opportunities.
For other suggestions...if you have a dog? walking a dog is a sure fire way to meet people. Same goes for cycling.
I have traveled solo often..and will be again for 6 weeks come mid-March, and yes, it can be hard. There are some dating sites...Plenty-of-Fish, for one, that also shows meeting times and places...people gather someplace, have conversation and on their way. You don't gotta be looking for a date..it just gives one a chance to meet people and chat.
